Though only about seven times the mass of the Sun, giant Atria emits more than 2,000 times as much light. It is believed to have a yellowdwarf companion somewhat similar to the Sun, whose interactions with its giantprimarystar result in frequent flare activity.
Atria is a highly luminous body, though as an orange, K-type, star its surface
temperature is a little lower than that of the Sun. There are indications of strong
flare activity on its surface, and a small and faint binary companion has recently been
detected.
