Where is interstellar comet Borisov? Track live*!

Borisov, also known as C/2019 Q4, is a mysterious visitor from deep space heading right for our solar system. The comet travels at a speed of 151,949 (94,417). It appears to come from another star, and is only the second interstellar visitor to our solar system. The first was ʻOumuamua.

Comet C2019 Q4 was discovered in 2019 by Russian astronomer Borisov. It is headed to pass through or Solar System close to Mars and is currently 327,087,171 (203,242,262) from Mars, getting closer to Mars every second. Its speed relative to Mars is 23,111 km/h (14,361 mph).

Comet 2019Q4 appears to be an active comet, showing a broad, short tail pointing away from the sun, which is typical for a comet. This is the first interstellar comet that is observed. Visually the object looks a lot like the comets of our own solar system. Borisov has a reddish, carbon-rich surface. It is releasing 170 grams of cyanide every second as comet Borisov's icy surface melts under influence of the sun. [Alan Fitzsimmons et al, 2019]

Since last night C/2019 Q4 is 531,068 km (331,917 mi) closer to Mars. Since you started looking at this page it is 0 km (0 mi) closer.

Will it hit or miss Earth?

Interstellar Comet C2019 Q4 was discovered very early - much earlier than ʻOumuamua, which means scientists have been able to take multiple observations and work out that its orbit means it will not hit Earth. Comet C/2019Q4 should be visible for many months, until about 2021, when it will become too far away to be studied by scientists. It's official name is now 2I/Borisov, with the 'I' being for Interstellar, but it was formerly also designated gb00234.
