As planets orbit the sun, inner planets pass the outer planets. Now is when the Earth is passing Mars. Mars is at opposition; it is opposite the sun in our skies. Mars is closer to Earth, making it larger (although quite small) and brighter. To see it in its splendor, look east after sunset. On Oct. 21, Mars rises at 6:18 p.m.
