This asteroid does not have the potential to collide with Earth, at least until the next century.
2. Perige Bulan
Moon perige is a configuration when the Moon is closest to Earth.
Researcher from the National Institute of Aeronautics and Space Science Center (Lapan), Andi Pangerang said that the moon’s perige was caused by the moon’s elliptical orbit with Earth located at one of the focal points of the orbit.
As for, perige Bulan occurs every 27 one-third of the day on average with intervals of two adjacent lunar periods varying from 24 5 per 8 to 28 half days.
Andi, in his written statement on the Lapan science education page, said that the Moon Perige in March 2021 will occur twice.
The first occurred today on March 2, 2021 at 12.26 WIB, 12.26 WIT, 14.26 WIT with a distance of 365,399 kilometers from Earth (geocentric), 89.1 percent illumination and around the Virgo constellation.
“Meanwhile, the second month perige occurred on March 30,” said Andi.
