Physically Skat is classified as a main sequencestar like the Sun, though it is considerably larger and more massive, with a diameter between twice and five times that of the Sun. An old star for its type, Skat appears to reaching the point where its hydrogen reserves are nearly consumed, and beginning the transition into a subgiant and ultimatelty a giantstar.
There are some slight indications that Skat may have a binary companion, but calculations suggest that this companion would orbit just two Astronomical Units from the primarystar. The existence of this companion is therefore debatable at best.
The origins of the name Skat are also subject to some debate. It seems to have originally had the form Scheat, a name shared with Beta Pegasi, and this may have been transferred to the star in Pegasus in error (Pegasus lies on the northern border of Aquarius). Various interpretations of the name are proposed, but perhaps the most likely is Arabic al-sāq, 'the shin' (and indeed traditional star-maps show Skat as marking the shin of Aquarius the Water Carrier).
