Epsilon Trianguli

Based upon measurement of its trigonometric parallax, it is approximately 390 light years from Earth.

[1] The primary component is an A-type main sequence star with a stellar classification of A2 V,[3] an apparent magnitude of +5.50 and an estimated age of 600 million years.

[7] The secondary component has an apparent magnitude of 11.4 and is separated from the primary by an angle of 3.9 arcseconds.

[12] An excess emission of infrared radiation suggests the presence of a dusty disk in orbit about the primary.

This disk has a mean radius of 105 AU, or 105 times the separation of the Earth from the Sun, and is radiating at a temperature of 85 K.[7] This star system is a probable member of the Ursa Major Moving Group of stars that share a common motion through space.
