Jupiter.

Tomorrow ... Earth passes between the sun and Jupiter, placing Jupiter opposite the sun in our sky. Astronomers call this event an opposition of Jupiter. The 2010 opposition is Jupiter’s closest since 1963. Plus, Jupiter is near tomorrow’s moon.

The giant planet is now lighting up the September night from dusk until dawn. It will remain close and bright throughout the second half of September. Although it’ll dim slightly by October, more people will notice Jupiter next month, because it will appear in the east already as the sun is setting in the west.
