NASA is looking forward to this weekend's supermoon. That's when the moon appears bigger and brighter because it's the closest it will be to earth all year.

ABC7's Adam Caskey visited Goddard Space Flight Center in Greenbelt Tuesday morning. Dr. Michelle Thaller, a NASA Scientist says the moon will appear about 14 percent larger and 30 percent brighter than a typical Full Moon does.

The Moon will be at its closest distance to the Earth at exactly 7:32 a.m. on June 23, but you can still see it on the night of the June 22 as well.

Supermoons occur when the moon reaches the lunar perigee - its closest point to the earth on its elliptical orbit around Earth. ABC7's Eileen Whelan pointed out last year that the Earth's perigee is about 50,000 kilometers closer to our planet than its apogee, which is the moon's longest distance from Earth.

In 2012, a supermoon was able to be seen on May 6, and a 2011 supermoon was visible on March 19.
