Proper Name	Acamar (properly the name of the Theta¹ component of this binary system)
Bayer Designation	Theta^1,2 Eridani
Flamsteed Number	None
HR (BSC)	897 (Theta¹ Eridani) 898 (Theta² Eridani)
HD	18622 (Theta¹ Eridani) 18623 (Theta² Eridani)
Constellation	Eridanus
Right Ascension	2h 58m 16s
Declination	-40° 18' 17"
Distance	161 light years 49 parsecs
Magnitude	Apparent: +3.2 (Theta¹ Eridani), +4.3 (Theta² Eridani) Absolute: -0.3 (Theta¹ Eridani), +0.8 (Theta² Eridani)
Spectral Class	A5IV white subgiant (Theta¹ Eridani) A1V white main sequence star (Theta² Eridani)
Optimum Visibility	November
Notes	Theta Eridani is a widely-spaced binary star, of which the traditional name Acamar is formally applied to the Theta¹ subgiant component. There is reason to think that this subgiant - which is beginning its transition to the red giant phase of its existence - has another star in a much closer orbit, making Acamar a multiple system.

A binary star in the River Eridanus. Both components are hot white, A-type stars, but one is a subgiant while its companion is a smaller dwarf star. The entire system lies nearly 170 light years from Earth.
