A Day on Another Planet

A day refers to the amount of time it takes for a planet to complete a single 360-degree rotation on its axis. On Earth, that’s 24 hours. But the other planets in the solar system rotate at faster or slower speeds, and their day lengths vary accordingly.



On Mercury, a single day amounts to 58 days and 15 hours Earth time. In contrast, the planet’s years are extremely short: only 88 Earth days. This is because Mercury moves more quickly around the sun, abbreviating its years, while its speed of rotation is slow enough to prolong its days.


Of all the planets in the solar system, Venus has the longest day. Its equivalent is 243 Earth days, while its year only consists of 224.7 days, essentially making its days longer than its years. The reason for the discrepancy is its slow rotation speed: while the velocity of the other planets have flattened their poles, Venus has not leveled out anywhere. It also rotates backwards, an oddity that some astronomers attribute to a massive impact with another planet billions of years ago.


A day on Mars, which is referred to as a ësol’, consists of 24 hours, 39 minutes, and 35 seconds, making its days similar to Earth time. This is one of many reasons why scientists asserted that plant and animal life could exist on the Red Planet, as Mars is also called. A Martian year lasts 686.98 Earth days, which translates to approximately 1.88 years.


Jupiter is the largest planet in our solar system, but it also happens to have the shortest day (9.9 Earth hours), because it rotates more quickly than any other body in the solar system. Its rapid rotation speed has caused extreme flattening at the poles and a bulging equator line.

Scientists had difficulty determining day length on Jupiter because it lacked surface features that could be used to calculate its rotational speed. At first storm centers were used, but Jupiter’s storms moved so rapidly that results were inconclusive. Rotational period and speed were finally determined by assessing radio emissions from the planet’s magnetic field.


The length of a Saturn day has proven to be extremely difficult to calculate, as the plant is a giant gas entity as opposed to terrestrial like Earth or Mars. The first estimation, which was attempted back in the 1980s, was 10 hours, 39 minutes and 24 seconds in Earth time. A second attempt delivered a result of 10 hours, 45 minutes, and 45 seconds. Using more advanced equipment in 2006, astronomers came up with a measurement of approximately 10 hours and 47 minutes. Some members of the scientific community assert that the length of a day on Saturn will never be known for certain.


A day on Uranus is the equivalent of 17 hours, 14 minutes, and 24 seconds on Earth. Because its axis is tilted to nearly 90 degrees, Uranus actually rotates on its side instead of spinning like a top. As a year progresses, one of its hemispheres faces the sun’s light while the other is in darkness for a complete season. What this means is that the planet’s days and seasons are one and the same. Day is as long as summer, and night is as long as winter.


On Neptune, a day translates to 16 hours, 6 minutes and 36 seconds on Earth. Since the planet is mainly gas, different parts actually rotate at varying speeds, a process known as differential rotation. Neptune’s equator zone takes around 18 hours to rotate, while the polar regions complete a cycle in 12 hours. Scientists attribute the large difference in rotational rate to Neptune’s winds, which can go up to 2,400 km/hour, making them the strongest in the solar system.

Spring 2015 Clock Contest Winners

THANK YOU to all who participated in our Spring 2015 clock contest! So many great stories – we truly appreciate the opportunity to hear about all of the great projects our customers have accomplished.

Congratulations to the grand prize winners: Erin Keck (most creative), Roger Carson (gift of time), and David Schermock (best use of parts). See each of their photos below and read their stories behind the clocks. Also, please join us in congratulating the finalists!

Most Creative Clock – WINNER: Erin Keck


“I am an Art Teacher and Gallery Artist residing in Mechanicsburg, PA. I teach at Art Retreats and Schools throughout the U.S. using Klockit parts. My Original Steampunk Style Clocks are recognized and known Internationally.

I came up with the idea of creating these clocks after seeing an antique mechanical clock where all of the gears revolved. I wanted to create clocks that gave the illusion of movement by remaining stationary and running on a Quartz battery movement.

I design and cut each gear in my clocks from wood. The gears are then painted to look metallic. I give the illusion of movement through balance, dimension, and adding found objects.”

Congratulations to Erin Keck!

Gift Of Time – WINNER: Roger Carson


“My wife Tiffany and I have lived at our current home for 7 years and previous to this lived one street over for 4 years. We became well acquainted with the area residents over this time. We didn’t meet Joella until we moved to our current home in 2007. Jo, as she prefers to go by, is a self sufficient, caring elderly widowed lady from Texas that wouldn’t take anything from folks willingly. The kind of elderly neighbor my wife and I grew up around that we don’t find too much of these days. Over the last three years Jo started to have some health issues. This was about the only thing I saw that slowed down Jo. Her son and daughter traveled from the west coast and decided it was time to move her into an assisted living home where she could live free but still have caretakers on site when needed. Her children discussed with us the decision as we were close to Jo and wanted us to be part of helping Jo transition.

When it came time to help the family clear out Jo’s home her son asked my wife to help him in the basement. There, on a bench under some old pictures was a wall clock kit that was about 1/2 completed. He told my wife we could have it, that he would love to keep it and finish it but wood work wasn’t his thing. He said his dad, Al, loved wood working and his dad started the clock for Jo shortly before his death- in 1994.

As soon as my wife told me the story we both knew that clock was getting finished somehow. I retrieved the clock and all the pieces of trim, etc… I could find and started the ‘puzzle’ of completing the assembly. Jo’s son said his dad couldn’t decide on a mechanical or “new-fangled” electronic movement. We wanted to make this stand out but Jo has hearing issues so I decided to go with the rotating crystal movement without sound. I was able to figure out where most of the trim pieces went (I hope) and purchased some hinges that I managed to fit to Al’s pre cut hinge mortices. I knew from all the fine hand crafted furniture Jo’s husband had made over the years that a darker stain was in order so I used a red Mahogany with 3 coats of gloss lacquer.

We stopped at Jo’s assisted living home just before Christmas to offer her the clock that she had completely forgotten about. She was so surprised she had to sit down for a few minutes to take it all in. I hung the clock for her, listened to several more stories of her husbands love of wood working and got several hugs. The feeling my wife and I had from the smiles and joy we brought to Jo are like nothing we have ever experienced. Jo has called us several times and comments each time of the clock giving her a feeling of “home”, something she felt was missing in her assisted living apartment.

I have always wanted to make a clock and it was just amazing that this came into us at this time in our lives. It gave me some connection to Jo’s late husband as well as pushing me to finally wade into clock work.”

Congratulations to Roger Carson!

Best Use Of Parts – WINNER: David Schermock


“This clock is a “quartz movement version of the beautiful Jewelers Wall Clock” originally designed for a mechanical movement and found in all of the current Klockit catalogues. I have admired the Jewelers Wall Clock for quite some time but I typically don’t build clocks with mechanical movements so I passed over my mild obsession with this design and continued to build numerous other clocks.

As always the arrival of the latest Klockit catalogue caused me to sit down and browse through it looking for items I could use and gathering ideas for my next clock projects. The upcoming wedding of my granddaughter had me searching for something elegant enough for a wedding gift that would be appreciated and hopefully treasured as a family heirloom. I kept coming back to the Jewelers Wall Clock as the ideal candidate.

Sitting down with my latest Klockit catalogue I began going through it page by page identifying the various pieces I would need to build what I felt would be an outstanding example of a clock for the new generation newlyweds. As always, I found everything I would need to get started. In all, twelve part numbers and a lot of work would be necessary to build the clock.

This clock makes an outstanding project and the sound from the Quartz movement (12003) is incredible. With the choice of melodies, volume control and night shut off this movement can be tuned to any environment and room size. With the speaker mounted in the top of the case and tone quality of this movement, the chime fills the room(s) with full rich sound. I prefer the Westminster.

I built the prototype in red oak and it hangs proudly in the living room of my home. I built a second Jewelers type clock in rustic oak to blend with my
Granddaughter’s furniture style. I presented this second and most important clock to my Granddaughter and her new husband at their recent wedding. With their names and wedding date on a brass plaque attached to the lower rail of the door and my “Hand Crafted by” plaque inside, it commemorated the occasion perfectly. No other gift compared (my opinion).”

Congratulations to David Schermock!
