Interstellar objects GS3

A rare object entered our solar system last month and now astronomers have confirmed it is the second interstellar comet ever detected. It was given the name "2I/Borisov" , but researchers have no idea where it came from. IAU decided to follow the tradition of naming cometary objects after their discoverers.

In 2017, The Haleakala Observatory in Hawaii spotted a strange, spaceship-shaped object passing through the Solar System.

It was named “Oumuamua”, it became the subject of speculation whether it was really an alien spaceship.

It was eventually declared by scientists to be an interstellar object, the first such known visitor to the Solar System.

Now, a second interstellar object paid a visit.

On 30th August, Ukrainian amateur astronomer Gennady Borisov discovered the object from the MARGO observatory in Crimea which is believed to have originated from outside the Solar System,

1. Amateur and professional astronomers all over the world helped the IAU confirm details about the object. Observations from the group revealed it has an extremely hyperbolic orbit — meaning it is moving too fast to orbit the sun — confirming its origin as interstellar.

2. It is still inbound toward the Sun. It will remain farther from Earth than the orbit of Mars.

3. It was detected by NASA’s Jet Propulsion Laboratory (JPL), Scout system.

4. JPL automatically flagged the object as possibly being interstellar.

The comet’s current velocity is about 150,000 kph, which is well above the typical velocities of objects orbiting the Sun.

The high velocity indicates that the object likely originated from outside our Solar System and head back to interstellar space.
