While Mercury is closer to earth than most of the planets, it is still largely regarded as a rather mysterious planet. One other element that adds to the mystery of this planet is its moon situation.
How Many Moons on Mercury?
While most planets have a moon, Mercury does not, and neither does its next-door neighbor, Venus. This is due to a variety of factors. When it comes to Mercury, the planet’s gravity would not be able to hold a moon in place. The planet’s proximity to the blazing hot sun is always believed to play a roll. Due to the gravity situation, scientists believe that if Mercury had a moon, it would eventually get pulled into the sun after transferring to its orbit. Another therapy is that after a while, the gravity situation would result in the moon crashing into the planet.
How Planets Acquire Moons
To get a better idea about the moon situation on Mercury and how moons come to be, you want to learn about how the planets get them. This gives you deeper knowledge of the topic and makes it easier to understand why Mercury has no moons.
There is believed to be a few methods associated with this, such as a moon forming from a type of circumplanetary disk material, gravity from a larger body captures a smaller body and massive collisions. One example of the collision belief involves Mars. This is believed to be what led to The Moon. Approximately 4.5 billion years ago, a massive collision with an object the size of Mars occurred. In the aftermath, a moon resulted.
Now you know more about Mercury and its moon situation. While it might not have one, it does have multiple other characteristics that keep it quite interesting.
