Astronomers find asteroid giant hidden behind the glare of the sun. What are the chances of passing from Earth?
The asteroid, named 2022 AP7, belongs to the group found in the orbits of Earth and Venus, but is very difficult to observe because it is obscured by the sun’s glare from telescope observations. / 2022).
This asteroid is 1.5 km wide, the largest asteroid considered potentially dangerous to Earth in the past 8 years. That’s why astronomers nickname this asteroid “planet killer” aka planet killer.
To avoid the glare of the sun, astronomers make their observations during twilight. Astronomers who are an international team in several countries observe space rocks using the Dark Energy Camera located on the Víctor M Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile.
Asteroid It is thought that it may enter Earth’s orbital path in the future, but it is difficult for scientists to know when that will happen.
“Our twilight survey scours the area within the orbits of the Earth and Venus for asteroids. So far we have found two large near-Earth asteroids about 1 kilometer wide, the size of what we call planet killers,” he said. said lead author Scott S. Sheppard, an astronomer and co-author of the study at the Earth & Planets Laboratory at the Carnegie Institution for Science in Washington, DC.
Astronomers’ findings on this “planet-killer” asteroid were published yesterday in The Astronomical Journal on Monday (10/31/2022).
Astronomers determined that asteroids could cross Earth’s orbit, but this would happen when Earth was on the opposite side of the Sun – this pattern would continue for centuries as asteroids take five years to complete one orbit around the Sun But over time, the movement of the asteroid’s orbit will be more synchronized with the Earth.
Astronomers don’t know the orbit asteroid with enough accuracy to say how dangerous it will be in the future, but for now, “It will stay away from Earth,” Sheppard said.
