R Leonis is a red giant Mira-type variable star located approximately 370 light years away in the constellation Leo. The apparent magnitude of R Leonis varies between 4.31 and 11.65 with a period of 312 days. At maximum it can be seen with the naked eye, while at minimum a telescope of at least 7 cm is needed.

R Leonis boldly boasts to be one the brightest and easiest to observe variable stars in the sky. With a mean visual magnitude range of 5.8 to 10.0, this mighty star can easily be seen without the aid of any costly equipment.

R Leo is a deep class M (M8) giant, whose class also varies, between M7 and M9, giving it a lovely color described by Burnham as "rosy scarlet with often a seeming touch of purple."

Jan 29, 2025 · Like the prototype Mira, R Leo is a long-period variable star, a relatively cool, pulsating red giant star in the final stages of life. These bloated behemoths begin their lives …

R Leonis Minoris (R LMi) is a Mira variable type star in the constellation Leo Minor. It ranges between apparent magnitude 6.3 and 13.2, and spectral types M6.5e to M9.0e (Tc:), over a period of 372 days.

Like its kindred LPVs, R Leonis is a cool red giant – a dying star whose brightness changes result from internal pulsations. Based on recent observations, R Leonis has a magnitude in the mid-8 area and is rising to a predicted maximum later this month.

An entire night can be spent observing variables without ever leaving Leo’s boarders. This month we’ll dive deeper into one of the most often observed LPVs, R Leonis. R Leo is the 3rd most observed LPV in the AAVSO database (AID), behind …

Rho Leonis (ρ Leo), also named Shaomin, [9] is a binary star in the zodiac constellation of Leo, and, like the prominent nearby star Regulus, is near the ecliptic. With an apparent visual magnitude of 3.9, [4] this star can be readily seen with the naked eye.

Apr 2, 2021 · R Leonis is a cool red giant star nearing the end of its life. It is characterized as a long-period variable, much like the more famous Mira in Cetus. Its magnitude fluctuates between 5 and 10.5...
