Jupiter Near Opposition

October 24, 2011

Jupiter

On October 29 (UT), Jupiter, the solar system’s largest planet, will be at opposition, opposite the Sun in planet Earth’s sky, shining brightly and rising as the Sun sets. That configuration results in Jupiter’s almost annual closest approach to planet Earth, so near opposition the gas giant offers earthbound telescopes stunning views of its stormy, banded atmosphere and large Galilean moons.
