Summary:
- The 3i Atlas is a small asteroid that orbits the Sun and occasionally comes close to Earth.
- As it approaches Earth, the asteroid's surface is reflecting more sunlight, causing it to appear brighter and greener in the night sky.
- This increased brightness and greenish hue is due to changes in the asteroid's surface as it gets closer to Earth, which scientists are studying to learn more about the composition and characteristics of this near-Earth object.
