Falling into a Halley's Comet by AstroCinema。

Halley's Comet is one of the most famous comets。

It is a short-period comet，meaning it returns to Earth approximately every 75-76 years。

It was last seen from Earth in 1986 and is currently located about 35 AU away。

and is expected to return in 2061。

Its tail is made of gas and dust。

and it can be over 10 million kilometers long。

The surface temperature is between -70° and -30°C。

which is enough to heat the ice and turn it into gas。

Thanks for watching。
