Zosma

Designation: 68Del Leo · HIP 54872 · HD 97603

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

58.4 light-years away Apparent magnitude 2.56

A-type: white and crisp

Its spectral type is A4V: surfaces around 7,500–10,000 °C; Sirius and Vega are the classic examples. From its measured color, its surface temperature is roughly 8,766 K (8,493 °C), an estimate computed from the catalog's color index.

How far away is it?

It lies 58.4 light-years away (17.91 parsecs, from its measured parallax), within the Sun's wider neighborhood; its light is only 58.4 years old when it reaches your eye.

How powerful is it?

Its computed luminosity is about 26.4 times the Sun's output (derived from its brightness and distance).

Can you see it?

At apparent magnitude 2.56, it is an easy naked-eye star under any reasonable sky. It is visible from both hemispheres.

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.
