How long is a night in Mercury?

Mercury takes around 176 Earth days to revolve on its axis (from sunrise to dawn), whereas Earth only takes 24 hours. For one year on Mercury, it is day and for one year it is darkness. The sun never sets nor rises, but it does change position in the sky.

A day on Mercury is about 48 minutes longer than a day on Earth. The night is about half as long as on Earth, at about 22 hours.

The average temperature of Mercury is 450 degrees F (232 degrees C). However, there are huge differences between the surface of the planet and its interior. The core of Mercury is probably molten iron, while the outer layer is almost completely made up of ice. It is estimated that the entire inner body of Mercury is covered in ice.

Although most of Mercury is frozen, small regions near the equator experience very large tides caused by the gravitational interaction with Venus. These tides reach a height of more than 10,000 feet (3,050 m) above the surface!

It has been suggested that if Earth were to ever be colonized, then Mercury would make an excellent world because of its similarity to our own planet. Both planets have intense radiation environments and extremely thin atmospheres. They also have similar sizes and masses.

How long is a day in Mercury?

58d 15h 30m Day length/Mercury The time it takes a planet to revolve or spin once on its axis is referred to as its day. Because Mercury revolves at a far slower rate than Earth, a day on Mercury is significantly longer than a day on Earth. A day on Mercury lasts 58.646 Earth days (1407.5 hours), whereas a day on Earth lasts 23.934 hours. Mercury orbits the Sun every 88 days, but because of its low orbit it experiences extreme temperatures: -180&degC to 250&degC.

The day on Mercury is so long that a full orbit completes only around twice per revolution, which means that there are two nights and two days. However, because Mercury has no atmosphere to reflect light from the sun back to space, all parts of the planet receive direct exposure from solar radiation. Most regions experience a severe temperature change between sunrise and sunset, with the coldest point being inside the planet's cloud-covered magnetic pole.

Because of its distance from the Sun, Mercury has an extremely eccentric orbit, varying between 47.9 million km to 59.5 million km from the Sun. This results in many large swings in distance from Earth, with periods of 8 minutes to 11 hours. During these close approaches, the amount of sunlight received by Mercury increases, causing it to heat up for a few days before it moves away from us again. These encounters with our star also cause large changes in Mercury's rotation, since it's not strong enough to keep itself rigidly spinning in one direction.

Does Mercury have a shorter year than Earth?

A year on Mercury lasts around 88 Earth days. Mercury's year is the shortest of any planet in the solar system. Earth's year is approximately 365 days. The only other planet that orbits closer to the sun is Venus, which comes within about 57 million miles of our star.

Mercury has the fastest rotation of all the planets, taking 96 hours to complete one rotation. This means that at Mercury's north pole, day is equivalent to almost two Earth years; at its south pole, night lasts almost four Earth months.

The reason for Mercury's rapid rotation is that it is also close to being completely spherical. Because it has no internal heat source like Earth does, every time Mercury gets hit by a meteorite or satellite, its surface melts and flows like lava. This liquid metal then solidifies when the sun goes down, causing great stress on the planet's outer shell that eventually leads to failure. If Mercury were not spinning so fast, it would disintegrate over time.

Although Mercury is destroyed by intense heat, its core is probably molten iron or nickel. It is possible that there is some carbon floating around in the form of carbons atoms, but this has not been confirmed by any experiments or observations.
