Astronomers have recently discovered an asteroid that tags along with the Earth during its annual journey around the sun.
Named as 2023 FW13, this asteroid is considered by experts to be a “quasi-moon” or “quasi-satellite.”
- Quasi-moons are also known as ‘quasi-satellites‘ because they appear in the orbit of earth in the same way of Earth’s natural satellite, the Moon.
- But they are bound by the gravity of the Sun instead of the Earth. That’s why they are called Quasi. Whereas the moon is bound by the gravity of the earth.
- 2023 FW13′ was first spotted on March 28, 2023, by the Pan-STARRS survey telescope. This telescope is located on the top of Haleakala, a dormant volcano on the Hawaiian Island of Maui.
