Mercury's Solar Day is about 176 Earth days. That's the time taken for the Sun to complete one apparent journey around the sky.

Mercury's Sidereal day (rotation period) about 58.6 Earth days.

Earth's solar day is 24 hours.

Earth's sidereal day is about 23 hours and 56 minutes.

What is the smallest planet's period of rotation?

The smallest planet, Mercury, has a period of rotation of about 59 Earth days. Its slow rotation speed means that a day on Mercury (from one sunrise to the next) is much longer compared to a day on Earth.


Does 59 earth days equals 1 day on mercury?

No, one day on Mercury is equal to about 59 Earth days. Mercury's slow rotation on its axis causes this long day length compared to Earth's 24-hour day.

Which planet's day is closest in length to its year?

The planet Mercury has a day that is almost the same length as its year. Mercury's rotation period is about 59 Earth days, which is very close to its orbital period around the Sun of about 88 Earth days. This means that one day on Mercury is almost as long as one year on Mercury.


What is the name of the planet with the longest day compared to an earth day?

Venus. The length of "day" is 243 Earth days. That's the rotation period which is called a "sidereal day". However, there's also a "day" called the "solar day". That's the time for the Sun to complete one apparent journey around the sky. For that definition of "day", it is Mercury that has the longest day at about 176 Earth days.


What planet requires 59-60 earth days to complete one rotation on its axis?

The planet that requires 59-60 Earth days to complete one rotation on its axis is Mercury. Mercury is the closest planet to the Sun and has a slow rotation speed compared to its orbit around the Sun, resulting in a longer day-night cycle. This is due to its proximity to the Sun, which causes gravitational forces to affect its rotation.


Which planet has a day more than half as long as its year?

Mercury's "sidereal day" is about 59 Earth days long and its year is about 88 Earth days long. Venus has a "solar day" of about 117 Earth days and a year of about 225 Earth days.
