The compass graphic points to the object’s orientation on the celestial sphere. North points to the north celestial pole which currently lies near the star, Polaris, in the circumpolar constellation Ursa Minor. The object is observed at visible light wavelengths, the colors corresponding to the true emission of light from stars, galaxies and ionized gases.

Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
Object Description | The type of astronomical object. |
R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
