SS Virginis is a Mira variable star that appears with a strong red hue.

It varies in magnitude from a minimum of 9.5 to a maximum of 7.4[6] over a period of 361 days.

SS Virginis, like all carbon Mira variables, has a hydrogen-alpha emission line that varies widely, synchronized with the overall variations in light.

The hydrogen-alpha emission line becomes far more prominent as the star becomes brighter.

[6] Observations made in the near-infrared spectrum indicate that it has a radius of 500 solar radii, and its temperature is between 2405 and 2485 kelvins.
