Since Mercury is the planet closest to the sun, it will be examined first in our solar system. The only planet smaller than it is Pluto, making it the second-smallest planet in the solar system. It is also uninhabitable, in contrast to Earth, which offers a suitable environment for humans. Specifically, due to its low mass, it has minimal attraction (引劫, attraction) and is unable to retain the atmosphere on its surface. Nitrogen makes up the majority of its atmosphere, but even that is sparse, and oxygen is essentially nonexistent. Our knowledge of Mercury comes primarily from unmanned probe rockets. Additionally, images from probe rockets revealed its lunar-like surface. Large and small craters left behind by objects colliding with it, such as the moon, cover its surface.
Its volume will decrease with decreasing temperature, according to some astronomers who believe that iron is contained in its center. The surface is thought to be wrinkled or folded for this reason. By observing its cliffs and valleys, you can infer that it is feasible. You cannot see Mercury at night because it is so close to the sun. It is beside the sun at a point in the night sky when it is high (of course, during the day when the sun is up, you cannot observe the stars in the sky). When the sun is just below the horizon, you can occasionally see it shortly after sunset or before sunrise.
Additionally, the best time to observe Mercury is when it is farthest from the sun; unfortunately, the calendar we use cannot pinpoint this precise date. Astronomical magazines and websites that highlight stargazing also provide the best time to observe Mercury.
The planets in the solar system revolve around the sun. Revolution is when the planets in the solar system revolve around the sun and come back to their original position. They also rotate with revolution. Rotation is when we first created a calendar, We set the period of one rotation as one day and the period of one Earth revolve around the sun as one year.
The rotation of the Earth is the amount of time it spends rotating every day around an axis that goes through its center. The rotation and orbit of the planet in which we live influence our fundamental understanding of time.
Origins of the name Mercury Mercury's rotation around the sun takes only 87.971 days. From ancient times, Mercury was considered the god of speed by the Romans, who saw it revolve rapidly around the sun.
The mythical god of speed, Mercury, is comparable. Wearing winged shoes and a hat, Mercury is a messenger of the gods. These were Mercury's means of quickly informing the gods. Mercury was given this name for this reason.
