Orbit from osculating elements
2I/Borisov is placed by solving a Keplerian orbit at the simulation time (a = -0.9 AU, e = 3.36, i = 44.1°).
First confirmed interstellar comet. Discovered August 2019 by amateur astronomer Gennadiy Borisov. Showed typical cometary activity.
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.
2I/Borisov is placed by solving a Keplerian orbit at the simulation time (a = -0.9 AU, e = 3.36, i = 44.1°).
2I/Borisov: mean radius 0.2 km. These values are bundled with the object record and drive the rendered size.
The surface is a procedural shape unless a source record above says otherwise. It is not a measured shape model.
The short description and the fact list are written by the Space Time authors for orientation. They are not quoted from a catalog field and carry no citation of their own.
