Why doesn't Mercury have a moon?

Answer 1

Probably lots of things.

It is closest to the sun, it has the thinnest atmosphere, it has the largest iron core compared to it's overall size, it is the smallest planet, and it has the most eccentric orbit.

Answer 2

Mercury is much smaller, much closer to the Sun, and has no moons.

Mercury is hotter on one side than Earth, and colder on the other side. Mercury has no real atmosphere, no liquid water, and apparently no lifeforms.

A solar day on Mercury is about 176 Earth days, or twice as long as its year (88 Earth days). Its slow rotation and comparatively shorter orbit create this strange situation.

Answer 3

One theory is that Mercury's proximity to the sun would make it difficult for a moon to orbit around it without being pulled away. Additionally, any moons that may have existed could have been captured by the sun's gravitational force. Mercury's small size and lack of a substantial atmosphere may also contribute to the absence of a moon.

Answer 4

Mercury has too little gravity to keep a moon in orbit around itself.

Answer 5

The Moon was formed when a Mars-sized object impacted Earth, where Mercury was formed by material that clumped together after the sun was formed.

Answer 6

mercury looks like a moon because it is livee

Answer 7

Mercury is the closest planet to the sun and Venus is the second closest. Mercury is smaller than Venus.
