Jakarta, Borneo24.com – Do you know how the order of the planets in the solar system from closest to the sun to farthest? If sorted by the distance closest to the sun, then the order is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
After understanding the order, it means that Mercury is the planet closest to the sun. This is the reason why this planet is called the hottest planet in the Solar System.
In the Inner Planets group, Mercury is the smallest planet with a diameter of about 4.878 km. The Inner Planets are the planets closest to the Sun, such as Mercury, Venus, Earth, and Mars.
While the Outer Planets are the planets farthest from the Sun, such as Jupiter, Saturn, Uranus, and Neptune.
In the Solar System there is an asteroid belt, which is thousands of asteroids that revolve around the sun and are located between the planets Mars and Jupiter. This asteroid belt provides the boundary between the Inner and Outer Planets. So, so that we get to know more about interesting facts about Mercury, see the explanation here.
Water Can Freeze on Mercury
We know that Mercury is closest to the sun, so it is called the hottest planet. However, it turns out that at night, on Mercury the water can freeze because of the cold temperatures.
Reported from Science Alert, the temperature on Mercury at night can reach -180 degrees Celsius. In addition, on Mercury there are places that always experience eternal darkness. This condition occurs because the polar regions of Mercury are never exposed to sunlight. NASA’s MESSENGER spacecraft visited the planet Mercury in 2011.
There, water ice deposits were found that did not change shape. This can happen because the ice deposits are located at the poles that have never been touched by sunlight.
Its revolution is 4 times faster than Earth
Each planet undergoes a revolution, or the rotation of the planets around the sun, so that there is day and night.
according to Ask an Astronomer, blog run by astronomers at Cornell University in Ithaca, New York, United States, the earth’s revolution is moving faster. Earth revolves around the Sun at a speed of about 67,000 miles per hour or 110,000 kilometers per hour.
This speed measure is of course higher than the maximum speed of any jet aircraft. However, Mercury moves with a faster revolution than the earth, which only takes 88 days to circle the earth.
This happens because the diameter of the planet Mercury is the smallest compared to other planets in the other Inner Planets group.(***)
