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.

∙ 14y agoMercury takes 59 Earth days to rotate once and 88 Earth days to complete an orbit of the Sun. This means that a solar day on Mercury lasts about 176 Earth days, which is about twice as long as Mercury's orbital period. As a result a Mercury year is about 0.5 Mercury days long and one Mercury day lasts approximately two Mercury years.
If you think that this is strange it is because like the Moon and Earth, Mercury's slow rotation means that it ALMOST keeps the same side facing the Sun as it orbits the Sun.

That's called a "sidereal day".
The Earth rotates once in 23 hours 56 minutes and 4 seconds.
There's also the "solar day" which depends on the apparent movement of the Sun in the sky. That depends on a planet's orbital motion around the Sun, as well as its rotation period.
Earth has a "solar day" of exactly 24 hours. (Strictly speaking this is called the "mean (average) solar day".)
Unlike for Earth, Mercury has a huge difference in the lengths of the two "days".
The length of Mercury's solar day is about 176 Earth days.

∙ 13y agoMercury take around 87.97 days to make one orbit of the sun, about 3 Earth months for one year on Mercury.

∙ 11y agoNo - Mercury's "sidereal" day (rotation period) is about 58.6 Earth days.
Mercury's "solar" day is 3 times longer still, at about 176 Earth days.

Which planet has its year only 88 earth days long?
Mercury is the planet with an 88-day year.
What is the Length of day in earth hours for planet mercury?
58.6 Earth days x 24 for hours
A planet that spins once ever 59 earth days?
1 Mercury day is 59 Earth days
A planet has a very long day compared with earth .What does that tell you about the movement of that planet?
It means the planet rotates slower. To be precise, the angular velocity is less.
What is mercury's day length?
Mercury is the closest planet to the Sun in our Solar System. It rotates very slowly on its axis. The length of one day on Mercury is equal to 58 days, 15 hours and 30 minutes on Earth.
Which planet has its year only 88 earth days long?
Mercury is the planet with an 88-day year.
Which terrestrial planet has a day that is over two Earth months long?
Mercury.
How many earth hours in one planet mercury day?
4222.6 hours.
What is the Length of day in earth hours for planet mercury?
58.6 Earth days x 24 for hours
A planet that spins once ever 59 earth days?
1 Mercury day is 59 Earth days
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.
What planet requires 59-60 earth day to complete one rotation on its axis?
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.
A planet has a very long day compared with earth .What does that tell you about the movement of that planet?
It means the planet rotates slower. To be precise, the angular velocity is less.
How long a day in mercury?
>>10 hours / small planet= quicker rotation This is flase. The size of the planet does not have much to do with its rotation rate, particularely in a planet made of silicate. Stars in general change their rotation rate with time and people believe it may be related with generation of magnetic field for example. The planet Mercury rotates very slowly. While Earth has a solar day OS 24h Mercury's solar day is about 176 Earth days. It takes Mercury around six months to give a full turn over its own axis.
How long does it take mercury to complete one revolution?
Mercury completes one revolution in about 88 Earth days. This is due to its slow rotation. Mercury is a terrestrial planet that is the nearest to the sun. A day on Mercury is about 58.5 Earth days.
What is Mercury's rotation period and what does rotation mean?
mercury's rotation period is 58.647 earth days. a rotation is when the planet turns around on its axis, like what the earth does once every day.
