Does Mercury rotate?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete. (This is assuming an observer is not at one of the poles.

Is the gravity on Mercury stronger than Earth?
Since Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.
What if Earth was bigger?
If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently. May 19, 2011

Why havent we gone to Mercury?
Compared to other planets, Mercury is difficult to explore. The speed required to reach it is relatively high, and its proximity to the Sun makes it difficult to maneuver a spacecraft into a stable orbit around it.
What would happen if we landed on Mercury?
Because of its proximity to the Sun, Mercury receives the most intense solar radiation of all the planets. This means that, even with protection from the temperature, exposure to daylight on Mercury would be lethal, so human settlers would have to stay out of the Sun permanently. Nov 6, 2021
Does Earth have 3 moons?
After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Scientists discovered two extra moons of Earth apart from the one we have known for so long. Earth doesn’t have just one moon, it has three. Nov 7, 2018
Do we have 2 moons?
