What you need to know about the biggest supermoon in 68 years

Did you miss last night's supermoon? Not to worry -- you get another chance tonight.

NASA scientists say you will still get a great view of the supermoon tonight.

"I've been telling people to go out at night on either Sunday or Monday night to see the supermoon," said Noah Petro, deputy project scientist for NASA's Lunar Reconnaissance Orbiter (LRO) mission. "The difference in distance from one night to the next will be very subtle, so if it's cloudy on Sunday, go out on Monday. Any time after sunset should be fine. Since the moon is full, it'll rise at nearly the same time as sunset, so I'd suggest that you head outside after sunset, or once it's dark and the moon is a bit higher in the sky. You don't have to stay up all night to see it, unless you really want to!"

This is our largest, brightest supermoon since 1948.

This supermoon will be a little bigger and a little brighter than normal.

That's because on that day the Moon will be closer to Earth than it's been in nearly 69 years.

The term supermoon has made its way into pop culture over the past few years to describe a full moon that appears larger and brighter than normal.

The reason for this rare proximity is due mostly to the fact that the Moon's orbit around Earth isn't a perfect circle but instead is slightly elliptical. On average, this orbit is 238,900 miles (384,400 km) away, but it's about 5% closer to Earth at perigee and 5% farther away at apogee.

According to NASA, if you miss this supermoon, you will have to wait until Nov. 25, 2034, to see a supermoon appear this large again. To see it for yourself, just head outside after sunset tonight.
