HIP 64289

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

108.6 light-years away Apparent magnitude 10.95

Temperature from its color

No spectral type is recorded, but its measured color implies a surface around 6,234 K (5,961 °C), computed from the color index.

How far away is it?

It lies about 109 light-years away (33.3 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,917.

How powerful is it?

Its computed luminosity is only 0.0403 of the Sun's output, a modest lamp by stellar standards (derived from its brightness and distance).

Can you see it?

At apparent magnitude 10.95, it is a telescope target only. 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.
