Spectacular Planetary Conjunction
Posted Monday, July 7, 2008, at 11:14 AM<< Previous | Respond | Email link | Next >>
If you look in the West, about 9PM, for the next several nights, you can see a spectacular conjunction of 2 planets. Saturn (the upper white "star"), and Mars (the reddish lower "star" will get closer together until, the night of the 10th, will be the closest they will be for another 14 years. They just appear close, of course. At the speed of light, Mars is about 18 minutes away, while Saturn is about 83 minutes away (about 800 million miles further away). Last night, the Moon joined the lineup (see photo)-it is about 1 1/4 light-SECONDS away, a close neighbor to our earth. Below and to the right of the Saturn-Mars lineup (also in the photo) is Regulus. Although one of the closest stars, it is about 77 YEARS away at the speed of light! |
