Big, Bigger, Biggest
Although the Sun looks small from Earth, it is really much, much bigger than our planet (and any other planet in the solar system). The Earth is actually one of the smaller planets compared to the giant planets in the outer solar system - Jupiter, Saturn, Uranus, and Neptune. The table below lists the diameters of the planets and the Sun compared to the Earth.
