HIP 37186

HIP 37186 · HD 61856

A real star from the HYG catalog in the constellation Carina.

2,233.9 light-years away Apparent magnitude 7.88

M-type: red dwarf

Its spectral type is M0III: the galaxy's most common stars: small, cool, dim, flare-prone, and able to burn for trillions of years. From its measured color, its surface temperature is roughly 3,494 K (3,221 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies about 2,234 light-years away (684.9 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year -207.

How powerful is it?

Its computed luminosity is about 287.9 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 7.88, it is invisible to the naked eye, though binoculars will show it. It favors southern observers.

Everything above is computed from the catalog’s measured values for this star. Where a value is missing, the statement is omitted rather than guessed.
