Comet Swift-Tuttle

Comet Swift-Tuttle 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. It was discovered by Lewis Swift and Horace Parnell Tuttle Independently.Its orbit takes 133.28 years to travel round the Sun.

The absolute magnitude of the object is 4.5 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 139.3420 degrees. The Argument of Perihelion is 152.9141. 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 1992-11-29 at which point it was 0.950324 A.U. distance away.The Semi-Major Axis of the orbit is 26.092, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which Comet Swift-Tuttle orbits in relation to the orbital plane is 113.607 degrees. The orbital eccentricity is 0.963566, it is the degree at which Comet Swift-Tuttle orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
