Three related unknowns of major scientific interest concerning Mars are the size and the shape of the planet and the extent of surface topographic relief. Both local topographic relief and continental-scale topographic differences can be considered, along with the planetary ellipticity, as differences ...

Mars has two small satellites. Even the larger one is no more than 13 km in radius. Unlike the Moon, they are not round in shape. 火星有两颗很细小的天然卫星,较大一颗的半径也不到13km它们都不是球形的,却倒像两颗马铃薯。 www.lcsd.gov.hk 7. So, instead of measuring things in feet or...
If the acceleration of gravity on the planet's surface is 14.0 m/s2, what is the radius of the planet? The mass of the Mars is about 0.11 the mass of the earth, its radius is 0.53 that of the earth, and the...
The vast majority of asteroids can be found orbiting the Sun between the orbits of Mars and Jupiter. Asteroids tend to be irregularly shaped but Ceres is a notable exception in that it is spherical like a planet and has been upgraded to Dwarf Planet status.Asteroids...
