The only "supermoon" of 2017 lit up the sky last night. A supermoon is a full moon that coincides with its closest distance to Earth, resulting in a larger-than-usual apparent size of the lunar disk as seen from Earth.
The moon's elliptical orbit takes it about 30,000 miles closer to Earth (perigee) some months than others (apogee).
If you didn't get to see the moon tonight, don't fret - there will be two more supermoons early next year, on January 2 and 31.
The next super moon will be on January 1, 2018. Icerink opened for skating at full moon. Often cast in a reddish hue because of the way the atmosphere bends the light, totally eclipsed Moons are sometimes called 'blood Moons'.
"The supermoons are a great opportunity for people to start looking at the moon", said Noah Petro, a research scientist from NASA's Goddard Space Flight Center.
Astronomers say the best time to catch a glimpse of it is either right after sunset, or minutes before the next sunrise. You obviously can't tell from just watching it, but the moon orbits the Earth in a slightly oval-shaped path.
Considering the moon is always more than 225,744 miles away, it's not a major change.
Do you know at what phase a supermoon occurs?
