73P/Schwassmann-Wachmann is a comet, a celestial body that travels in from the far reaches of the cosmos that when it gets closer to the sun begins to burn away and produce a long tail. It is composed mainly of ice and dust.

The absolute magnitude of the object is 11.5 which is the brightness of the object. A higher absolute magnitude means that the object is faint whereas a very low number means it is very bright.

The Longitude of Ascending Node of the object is 69.6577 degrees. The Argument of Perihelion is 199.4074. It is the angle along the orbit of a planet or other Solar System object as measured from the ascending node (analogous to right ascension and longitude) Ref:Hawaii.

The closest the Comet came to its orbitting target was 2017-03-17 at which point it was 0.972049 A.U. distance away.

The orbital inclination, the angle at which 73P/Schwassmann-Wachmann orbits in relation to the orbital plane is 11.2382 degrees. The orbital eccentricity is 0.685715, it is the degree at which 73P/Schwassmann-Wachmann orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
