Feb 6, 2015:
Every 13 months, Earth and Jupiter have a close encounter. Astronomers call it an "opposition" because Jupiter is opposite the Sun in the sky. Our solar systemís largest gas planet rises in the east at sunset, and soars overhead at midnight, shining brighter than any star in the night sky.
This year's opposition of Jupiter occurs on Feb. 6th. It isn't an ordinary close encounter with Earth (approximately 640 million kilometers), but in Feb. 2015, Jupiter is edge on
to the Sun.
