This is a fourteener, thought not prominent enough to be considered its own mountain. Starlight's big brother would be the nearby North Palisade, both taller and larger than Starlight.
The true summit of Starlight is a very pointy, obelisk-like 30' boulder. It is most easily ascended by 5.9 moves on the East side.
Starlight can be accessed fairly quickly from North Pal. Either take one of the North Palisade routes up, or bag all the nearby fourteeners in the Palisade Traverse.
Starlight, as well as all of the other peaks in the North Palisade group, can be accessed by the East side (Palisade glacier) or the West side (Thunderbolt Pass).
