How to use this page
Choose your place and a night at the top. The page shows when the star rises, is highest and sets, where to look, and the star in 3D on the sky. The facts below give its brightness, distance, colour and type from the HYG star catalogue.
Frequently asked questions
How far away is this star?
The distance comes from its parallax, the small shift seen as Earth goes round the Sun, as measured by the Hipparcos and Gaia satellites and collected in the HYG catalogue.
Why do stars twinkle?
Turbulence in the air bends the starlight a little, many times a second. Stars low on the horizon twinkle most because their light passes through more air.
What does the colour of a star tell me?
Its surface temperature: red stars are the coolest and blue-white stars the hottest. The spectral type in the facts says the same in astronomers’ letters, from the hottest O to the coolest M.
