The asteroid 2007 FF1 has a diameter of 110-260 meters according to SpaceReference.com, a database that gathers information from NASA’s Jet Propulsion Laboratory (JPL) in California and the National Astronomical Union. economic. 2007 FF1 belongs to the Apollo asteroid group. This group includes about 15,000 asteroids whose orbits around the Sun cross the Earth’s orbit. Asteroid 2007 FF1 is classified as potentially hazardous due to its large size and relatively close orbit to Earth.
The Virtual Telescope Project took a blurry image of 2007 FF1 flying towards Earth on March 24, when the asteroid was 11.6 million km from us. This is the first evidence to confirm the asteroid will pass by Earth as predicted from previous models.
2007 FF1 will fly closest to Earth at 4:35 am on April 2, Hanoi time at a distance of 7.4 million km. Meanwhile, the average distance between the Earth and the Moon is 384,400 km, according to NASA. Thus, 2007 FF1 will fly 30 times farther from Earth than the Moon.
This is the closest flight to Earth of 2007 FF1 since its discovery in March 2007. In August 2020, this asteroid flew 17.3 million km from Earth and moved at 47,950 km / h, according to SpaceReference.org. The next close flight is estimated to take place on April 2, 2037 at a distance of 7.9 million km.
