1) Mercury rotates very slowly. It takes Mercury about 58.6 Earth days to rotate just once. That's the length of the sidereal day.
2) Mercury has a solar day of about 176 Earth days in length. So, Mercury's solar day is much longer than its long sidereal day. That's because of the combination of slow rotation with a short orbital period (about 88 Earth days).
What else can I help you with?
How many planets in your Solar System is larger than mercury?
As Pluto is no longer classed as a planet (It is now known as a dwarf planet), Mercury is the smallest. so there are seven planets larger than mercury.
What is Mercurys' radius with regard to the earth?
Earths mean diameter is 12756km at the equator, Mercury's diameter is 4879km. Mercury diameter is 0.3824 of Earths (if Earth is 1), or put another way, Earth diameter is 2.6 times bigger than that of Mercury.
Which planet is smaller than Venus?
Both Mars and Mercury are smaller than Venus. Pluto is also smaller than Venus, although it is no longer considered a planet.

You mean in OUR solar system. lol. Mercury is now the smallest because Pluto isn't considered a planet anymore.

Do any planets have longer days or years?
No two planets in our solar system have the same length of day or length of year. Compared with Earth, these planets have longer years: Mars, Jupiter, Saturn, Uranus, Neptune. These have much longer days than Earth: Mercury and Venus. Mars has a day that's slightly longer than Earth's day. Depending on the particular definition of "day" that is used, two planets have a day that's longer than than that planet's year. They are Mercury (solar day) and Venus (sidereal day).

What are the two smallest planets in your solar system?
Mercury is the smallest planet in the solar system, with a diameter of about 4,880 kilometers. Following Mercury, Mars is the next smallest planet in the solar system, with a diameter of about 6,780 kilometers.
What planets days are longer than your year?
Venus "sidereal day" is longer than its year. Mercury's "solar day" is longer than its year. However, there is no planet in our solar system with a day longer than our year on Earth.
Is mercury smaller or big then earth?
Not even close to it. The sun is about 864938 miles in diameter, while Mercury is only about 3032 miles in diameter. Actually, Mercury is not much larger than Earths moon. If you mean Mercury as in the plant, then no. The sun is the biggest thing in are solar system.
What are all the planets from big to small?
The planets in our solar system from biggest to smallest are Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Pluto is no longer considered to be a planet in our solar system, but is smaller than Mercury.
