The bus-size asteroid to throw on Earth this weekend



A bus-size asteroid will make a landing on Earth on Saturday.

The facility, called 2019 GF1, is between 8 and 18 meters long and will be nearly 1.8 million kilometers from the planet, data from the Jet Propulsion Laboratory (JPL) of NASA has been discovered.

For a typical object, it travels relatively slowly to 1.91 km / s – about five times the speed of sound – according to JPL.

"It moves through the sky very slowly because it orbits around the Sun with a similar rate on Earth," said South African Science Astronomer, Dr. Daniel Kunnama, for News24.

Even at 18 meters long, the 2019 GF1 is less than 2019 GC6, which appeared very close to Earth on April 9.

Massive size

The asteroid 2019 GC6 was discovered just nine days before its flight, Space.com reported, and is 30 meters wide.

It came close to 219,000 km. The moon is on average 380,000 km from Earth.

Asteroids usually orbital a belt between Mars and Jupiter, as well as outside Neptune in a region known as the Kuiper Belt.

They can be lifted from the orbit by impact or the weight of a large object.

These objects can then make their way to the inner solar system (between the Sun and Mars), where objects near the Earth (NEOs) are also known.

Kunama noted that the orbit of 2019 GF1 was close to that of the Earth.

"It seems to be in a very large orbit, a little by the orbit of the Earth."

2019 GF1 can be classified as Apollo asteroid because it crosses Earth's orbit, according to JPL data.

Other classifications include Amor (orbiting out of Earth's orbit) and Internal Earth Objects (orbiting Earth-Sun).

According to Spaceweather.com, there are about 1 967 potentially dangerous NEOs and scientists continue to discover new ones.

CAAO hosts asteroid asteroid instrument for last warning (Atlas) in Sutherland for monitoring dangerous asteroids.

The instrument is funded by NASA and costs $ 3.8m.
