Quasi-satellite 2023 FW13 confirms that it is not orbiting the earth and will stay near the earth for 1500 years.
CTOnews.com, May 31 (Xinhua) earlier this year, astronomers discovered a "quasi-satellite" suspected to be orbiting the Earth, which is known as "fake moon" in the industry. After careful observation, astronomers confirmed that the satellite was an asteroid called 2023 FW13, which did not orbit the Earth, but around the sun.
The 2023 FW13 is only 10-15 meters wide and is the size of a five-story building. Astronomical observers have attracted wide attention because of the asteroid's orbit and its expected to remain near Earth for the next 1500 years.
Fortunately, 2023 FW13 will not hit the earth and will not cause any danger to us human beings. CTOnews.com note: 2023 FW13, unlike our moon, orbits far from the Earth's "Hill ball" (the area around the planetary body).
The radius of the Earth's Hill sphere is 9.32 million miles (1.5 million km), while 2023 FW13 is about 1.6 million miles from the Earth.
