This is the first observed object from outside our solar system

Oumuamua is the first observed interstellar asteroid. It was discovered on October 19 and is about 800 meters long. Oumuamua is simply paying our solar system a visit as it continues its journey across the Milky Way.

There are most likely between one and 10 of these types of "visitors" per year in our solar system -- but they move so fast that we've never been able to see or study them.

'Oumuamua came from the direction of Vega, a bright star in the Lyra constellation. But even at 85,700 miles per hour, it took so long to reach our solar system that Vega wasn't in the same position 300,000 years ago.

The astronomers believe that instead, the object could have been traveling through our home galaxy, the Milky Way, for hundreds of millions of years, without being attached to any star system, before reaching us.

Because of its speed, if this type of interstellar object were to crash into Earth, it would have a much greater impact and create more energy than an object from our solar system.
