62). Hipparchus was the first astronomer to try to find out how far the sun was.
63). The red Mars is caused by rusting iron in the soil.
64). Jupiter has no surface for landing spacecraft because most of the surface is made of helium and hydrogen gas.
65). The largest satellite in the solar system is the Jupiter satellite, namely Ganymede.
