The Days (And Years) Of Our Lives
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Earth | 0.99 days | 365.26 days |
| Mars | 1.03 days | 1.88 years |
| Jupiter | 0.41 days | 11.86 years |

How old is Pluto the planet?
It was discovered in 1930 by Clyde Tombaugh and was classified for 75 years as the ninth planet of the Solar System.
How was Mars created?
When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle, and a solid crust.
How old is the moon?
4.53 billion years
Moon/Age
Scientists looked to the moon’s mineral composition to estimate that the moon is around 4.425 billion years old, or 85 million years younger than what previous studies had proven.
How old is Uranus?
4.503 billion years
Uranus/Age
Uranus was formed at the same time as the rest of the Solar System, from a large spinning disk of gas and dust. Astronomers think that all this happened about 4.6 billion years ago! So Uranus is about 4.6 billion years old.
Could life have evolved on Mars before Earth?
The discovery that ancient Mars could have supported microbes raises the tantalizing possibility that life may have evolved on the Red Planet before it took root on Earth. New observations by NASA’s Curiosity rover suggest that microbial life could have survived on Mars in the distant past , when the Red Planet was a warmer and wetter place, scientists announced Tuesday (March 12).
Is Mars a dead planet?
Geologically, Mars is a “dead planet” because it no longer is tectoncially active and hasn’t been for a very long time. Biologically, we really don’t know if it is dead. That is why scientists persist in search ing for evidence of life there.
What is the size of Mars compared to Earth?
Mars is roughly half the size of the Earth. It has a diameter of 4,222 miles, compared to Earth’s 7,962 miles at the equator. Mars is 53\% as large as Earth; this means that Mars has a gravity that is less than 40\% of what people feel on Earth.
