The interview

Short introduction:
Astronomers found a peculiar object in space that could be a sign of extraterrestrial life. The object is called ‘Oumuamua.

Summary:
He said that there is another peculiar fact about this object. He explained that when you look at all stars in the vicinity of the sun, the sun moves relative to them, but only one in five hundred stars in that frame is moving as slow as ‘Oumuamua. He also indicated that if this object came from another star, that star would have to be very special.

The interviewer asked him about some other strange facts about the object, in which he replied that it spins every eight hours, and its brightness changed by at least a factor of ten. He said that the most unusual fact about it is that it deviates from an orbit that is shaped purely by the gravitational force of the sun.

He asked him about the significance of that. He replied that it is nothing like a comet that we have seen before in the solar system. And it is also nothing like an asteroid. He saids that the only thing that came to his mind is that maybe the light from the sun, as it bounces off its surface, gives it an extra push.

The interviewer was wondering if this civilization would be out of the solar system and in the galaxy.
The astronomer said that It’s possible that the civilization is not alive anymore, but it did send out a spacecraft.
