I imaged Iota Cancri last night… Poor conditions, but cool colors!

Iota Cancri










The brighter star has the same surface temperature as our sun, but it’s 200 time brighter and has evolved off the main sequence. The fainter star is twice the mass of the sun, and revolves about its heavier companion every 60,000 years or so.

The stars are far apart from each other, some 2800 times the distance from the Earth to the Sun. A planet near the brighter star would see the fainter star shining as bright as the full Moon does in our sky. A planet near the fainter star would see the brighter star as 10 times as bright as the full Moon.
