Earth Has a New Temporary Natural Satellite
A Small Asteroid is Orbiting Our Planet
Astronomers have discovered a small asteroid that is currently orbiting Earth. The asteroid, which has been named 2020 CD3, is about the size of a car and is thought to have been captured by Earth's gravity about a month ago.
2020 CD3 is not the first asteroid to orbit Earth. In fact, there are several other asteroids that are known to be in Earth's orbit, including the famous Trojan asteroids. However, 2020 CD3 is the first asteroid to be discovered orbiting Earth in over a century.
What is a Trojan asteroid?
Trojan asteroids are a group of asteroids that share the same orbit as a planet. They are located at either of the two Lagrange points, which are gravitationally stable points near the planet.
There are two main groups of Trojan asteroids: the Jupiter Trojans and the Neptune Trojans. The Jupiter Trojans are located near the Lagrange points of Jupiter, while the Neptune Trojans are located near the Lagrange points of Neptune.
Trojan asteroids are thought to have formed at the same time as the planets they orbit. They are believed to be remnants of the protoplanetary disk, which was the disk of gas and dust that surrounded the Sun in the early days of the solar system.
What is the significance of 2020 CD3?
The discovery of 2020 CD3 is significant for several reasons. First, it is the first asteroid to be discovered orbiting Earth in over a century.
Second, 2020 CD3 is thought to be a relatively new addition to Earth's orbit. This suggests that Earth may be capturing more asteroids than previously thought.
Finally, the discovery of 2020 CD3 could help astronomers learn more about the formation and evolution of the solar system.
What is the future of 2020 CD3?
It is unclear what the future holds for 2020 CD3. It is possible that the asteroid will remain in Earth's orbit for many years to come.
However, it is also possible that 2020 CD3 will eventually be ejected from Earth's orbit. This could happen if the asteroid is perturbed by another asteroid or if Earth's gravity changes.
Only time will tell what the future holds for 2020 CD3.
