Planet Mercury is the planet closest to the sun. It is approximately 57.9 million km from the sun.
Because the distance is very close to the sun, this makes the sun’s gravitational force is higher than the planet’s gravitational force Mercury.
The gravitational force of the sun is greater than that of the planets Mercury this causes the absence of natural satellites that can orbit and are stable for years around the planet Mercury.
As for the planets Venus which does not have a natural satellite, one of the reasons is also because it is quite close to the sun.
In addition, there is a change in the rotation of the planet Venus also have an effect on this.
