How is solar system studied?

Answer 1

The solar system is studied largely by observations using telescopes, helioscopes, and related equipment; the Earth itself yields many clues about the nature of the solar system and can be studied directly. For chemistry and properties of distant planets, probes can be sent to the surface (such have already been sent to surfaces of Mars, Venus, the Moon, Titan, etc.) or to perform fly-bys to take pictures, radar surface mapping through dense clouds, perform spectroscopic analyses, infrared imaging, etc.
