Watch interstellar comet 3I/ATLAS live online tonight as it races toward the sun on a rare visit from beyond our solar system.

Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

The new interstellar comet's official name is 3I/ATLAS. It's officially the third known interstellar object to pass through our solar system, and it poses no threat to Earth.

The ultra-rare object is travelling at about 245,000 kilometres an hour and will fly deep into the solar system, skimming past Mars.

As the closest planet to the showboating sun and the fastest orbiting planet in our solar system, Mercury goes retrograde three to four times per year, more often than any other luminary.
