It lies among a dense cluster of low-mass pre-main-sequence stars in the Orion OB1a.

Over 200 members of the 25 Orionis stellar group have been found, mostly T Tauri stars with spectral types of K and M and masses less than half the sun's.

There are also around 60 hotter stars in the region, including the eruptive variable V346 Tauri.

With a mass in excess of 10 M☉, the star is expected to explode as a supernova.
