There are a bunch of them just depends on which solar system you want :) I found a few at findzer.com's general search and at Google. just add this to your igoogle and you can find answers to any question all day long http://www.google.com/ig/adde?synd=open&source=ggyp&moduleurl=findzer.com/googlegadgets/000018.xml
Mars has a longer year than Earth (about twice as long) and its day is 24 hours and 38 minutes long.
Mars, with a revolution period of 24 hours and 38 minutes.
Earth takes a bit less than 24 hours to complete one rotation (day). The day on Mars is a bit longer at 24.6 Earth hours.
Mars. It's slightly longer at about 24 hours and 37 mins, but this period of rotation is very similar to Earth's.
A "Day" relates to the rotation of the planet. The giant Saturn spins around, or rotates, once every 10 hours and 45 minutes. So it's "Day" is only 10 hours 45 minutes (earth hours) long. Whereas Earth spins slower so its day is longer.
The duration of Final Days of Planet Earth is 2.83 hours.
58.6 Earth days x 24 for hours
Mars has a rotational period (day) only slightly longer than Earth's 24 hours - at just over 24 hours 37 minutes.
no there has been a new planet discovered it is called blenit. 1 year on this planet is 24 hours 1 day is 1 hour its closer to the sun than mercury it is believed to be smaller than the earth but a lot bigger the Pluto
16.11 hours.
4222.6 hours.
The ratio will always be the same so the answer will be 500 to both questions
