Borisov

Borisov — interstellar comet, explore its interactive 3D model in Cosmoscope.

Explore Borisov in a live 3D Solar System. Follow its calculated motion and inspect real astronomical data, distances and orbital facts.

The first comet confirmed to come from another star, found by an amateur astronomer in 2019. Its gas was unusually rich in carbon monoxide — ice that formed around a different sun.

~32 km/s relative to the Sun, far from it

Nucleus

Under ~1 km across (Hubble) — illustrative shape

Trajectory

Open hyperbola (e = 3.36) — JPL SBDB, two-body

Explore Borisov in 3D

Cosmoscope places Borisov in the Solar System using astronomical ephemeris or orbital elements, updated for the simulation time. Explore its calculated motion, distance and orbital facts in the interactive 3D view. Accuracy depends on the orbital model and its valid time range.
