The radius of the planent venus is nearly the same as that of the earth, but its mass is only eighty percent that of the earth. if an object weighs w on the earth, what does it wiegh on venus

Size, Mass and Orbit:

Whereas Earth has a mean radius of 6,371 km and a mass 5,972,370,000 quadrillion kg, Venus has a mean radius of about 6,052 km and a mass of 4,867,500,000 quadrillion kg. This means that Venus is roughly 0.9499 the size of Earth and 0.815 as massive.Apr 7, 2016

Volume: 10.8321×10 km 9.2843×10 km

Mean Radius: 6,371.0 km 6,051.8 ± 1.0 km

Gravity: 9.8 m/s2 8.87 m/s

i need the answer to this too but idk it ; -;

temp rises, and expansion
