Constellation is an archetype of cards made by Nova. These cards were introduced in Dark Core of the Graviton Galaxy, gaining further support in Structure Deck: Cosmic Clash, Twilight Hour, Limit Break of the Duelist, Starter Deck Nova, and Return of the Light. This Deck is used by Yuka Tsukimori. These cards are based on the 88 modern constellations. The members of this archetype are predominantly LIGHT or DARK with effects that often work in the Graveyard.

Since many also have Level modding effects (this is primarily passed down to their sub-archetype, the "Starlight Constellation" cards), they can easily Synchro or Xyz Summon, if the situation fits." or " " in the Deck.
