The comet should be visible by telescope through September, before it gets too close to the sun, and reappear in December on the other side of the sun.

Officially named 3I/ATLAS, the comet was confirmed as having originated outside of Earth's solar system on July 3, according to the European Space Agency (ESA) and NASA. It is believed to be about 20 kilometers, or over 12 miles wide, according to the ESA and traveling at about 60 kilometers, or 37 miles per second relative to the sun.

The comet is the third known interstellar object to pass through our solar system and is expected to make its closest approach to the sun in late October
