22Gam PsA
HIP 112948 · HD 216336
A real star from the HYG catalog in the constellation Piscis Austrinus.
A-type: white and crisp
Its spectral type is A0III: surfaces around 7,500–10,000 °C; Sirius and Vega are the classic examples. From its measured color, its surface temperature is roughly 10,612 K (10,338 °C), an estimate computed from the catalog's color index.
How far away is it?
It lies about 215 light-years away (66.1 parsecs, from its measured parallax). The light reaching Earth tonight left it around the year 1,810.
How powerful is it?
Its computed luminosity is about 62.5 times the Sun's output (derived from its brightness and distance).
Can you see it?
At apparent magnitude 4.46, it is a naked-eye star under dark skies, washed out by city lights. It favors southern observers.
Not alone
The catalog records this star as a member of a multiple-star system: two or more suns bound in orbit around each other, a configuration roughly half of Sun-like stars share.
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.
