AH Velorum is a single yellow-white star in the southern constellation Vela. It shines with an average visual magnitude of about 5.70, ranging from 5.50 to 5.89, so it can be seen with the naked eye under good skies. The star lies about 2,700 light-years away and is moving away from us at roughly 26 km/s. It is a bright giant/supergiant of spectral type F7 Ib-II, with a surface temperature around 6,100 K. AH Velorum has about 7 solar masses, radiates roughly 930 times the Sun’s luminosity, and is around 50 million years old. Its composition is near solar.
AH Velorum is a classical Cepheid variable star. Its brightness changes over about 4.23 days, swinging from magnitude 5.50 to 5.89. It pulsates in the first overtone, which corresponds to a fundamental pulsation period of about 6.0 days. The star’s radial velocity is about +26 km/s relative to the Sun. It is also known by several other catalog names: HD 68808, HIP 40155, HR 3232, SAO 219587, and CD−46°3902.
