Today, the planet Neptune, eighth from the Sun, will be at opposition. What does that mean? In short, if viewed from above, the Sun, Earth, and Neptune would be in a straight line in t hat order, with Neptune exactly opposite the Sun in the sky as seen from Earth. End result: Neptune rises as the Sun sets and Neptune sets as the Sun rises. Problem: Neptune is roughly +8 magnitude, which means that you'll need a good star chart and a big telescope to find it. Oh, yes, experience helps a lot, too.
