Is a day on Mars longer than a year on Mars?

Answer 1

Yes. A day (rotation around its axis) on venus 240- something [earth] days. (I think its 243.) a year (rotation around the sun) on venus is only 225 earth days. a day on venus is longer than a year.

Answer 2

Yes and no. It depends on which "day" you mean.

Venus rotates very slowly on its axis. A "sidereal day" (rotation period) is about 243 Earth days.

There's also the "solar day". That depends on the apparent movement of the Sun around the sky. The orbital motion of Venus around the Sun combines with the rotation of Venus to give a solar day length of about 117 Earth days.

A "year" on Venus is about 225 Earth days. That's the time to orbit the Sun.

That means the sidereal day is longer than the year, but the solar day is shorter than the year.

Answer 3

A day on Mars is about 24 Earth hours and 39.6 Earth minutes. So the day lengths on Mars and Earth are just about the same.

Strictly speaking, that's the length of the "solar day". That's about a couple of minutes longer than the rotation period (called a "sidereal day").

Answer 4

The "sidereal day" on Venus (its rotation period) is longer than its year.

Venus takes 243 days to spin on its axis relative to the background stars, while it takes 224.7 days to orbit the sun. Although its spin on its axis is longer that its orbital period, an apparent (solar) day is 116.75 days, since it spins in the opposite direction from Earth and most other planets.

Answer 5

No, a day on Mars is slightly longer than a day on Earth (24.6 hours), while a year on Mars is approximately 687 Earth days.

Answer 6

A mars day is longer. Each Mars rotation takes 24 Earth hours and 39.5 Earth minutes. A mars day is about 25 hours long.

Answer 7

A day on Mars lasts 24 Earth hours and 39.5 Earth minutes (24.6 hours).

A year on Mars takes 687 Earth days.

Answer 8

Yes it is longer. There are 2 main definitions, but either way the Venus day is a lot longer than an Earth Day.

Answer 9

Longer - each Moon day is 29 1/2 Earth days.

Answer 10

A day is shorter on Uranus as it spins more quickly on its axis (in 17 hours 14 minutes and 24 seconds, compared with about 24 hours on Earth).
