2. About Asteriod LD2
• It is spotted by the ATLAS Project of Nasa (Asteriod Terrestrial Alert System). This
projects tracks the asteroids that may potentially hit the earth.
• Its special feature is this that it is an asteroid but at the same time it has a tail
like a comet.
• This type of asteroids are called “Trojan Asteriod”.
• Asteroid LD2 is found in the orbit of Jupiter. It orbits in the same orbit of
Jupiter.

5. What is a comet?
• A comet is an icy, small Solar System body that, when passing close to the
Sun, warms and begins to release gases, a process called outgassing. This
produces a visible atmosphere or coma, and sometimes also a tail.
6. Reasons behind LD2’s peculiar character?
• It may have been an asteroid but with ice and gas trapped inside it. Then, it
must have had hit some other asteroids that lead to the exposure of the ice to
the sun giving rise to a tail.
