Mars is one of the four terrestrial planets. It is the fourth planet from the Sun. Despite its small size, its distance from the Sun enables it to hold onto hydrogen, which enables it to have water. In the table that follows, the observed values are taken from Yoder (1995).[ 1] Go to table of characteristics.
