Supermoon 2019: Moon to put on a STAGGERING display in February as HUGE full moon rises
What is a Supermoon?
The Moon rotates around the Earth on elliptic orbit, periodically approaching and receding our planet at different times.
Lyle Tavernier, a NASA astronomer explains: “The Moon doesn’t orbit in a perfect circle.
“Instead, it travels in an ellipse that brings the Moon closer to and farther from Earth in its orbit.
“The farthest point in this ellipse is called the apogee and is about 405,500 kilometres from Earth on average.
“Its closest point is the perigee, which is an average distance of about 363,300 kilometres from Earth.
“During every 27-day orbit around Earth, the Moon reaches both its apogee and perigee.”
