Two calculations of the mass of Mercury are presented which are based on the totally linear simplex method by the author (1990) in which the equations of motion are not linearized. Transit circle observations of Venus are employed to study how variations in Mercury's mass affected the (O-C)...

Due to its mass, Mercury has a stronger gravity than one would expect given its small size. Mercury's gravity is about 38% of Earth's, which means that if you weigh 100 kg on Earth, you would weigh about 38 kg on Mercury. Orbit: Mercury's orbit is the most eccentric of all the...
