Musca
The pattern of the brightest stars resembles that of Ursa Minor, in that the stars form a pattern reminiscent of a bowl with a handle. Lying south-southeast of Acrux in neighbouring Crux is Alpha Muscae. It is the brightest star in the constellation with an apparent magnitude of 2.7. Lying around 310 light-years away, it is a blue-white star of spectral type B2IV-V that is around 4520 times as luminous and 8 times as massive as the Sun. The star is a Beta Cephei variable with about 4.7 times the Sun's diameter, and pulsates every 2.2 hours, varying by 1% in brightness. A nearby star of magnitude 13 may or may not be a companion star. Marking the fly's tail is Gamma Muscae, a blue-white star of spectral type B5V that varies between magnitudes 3.84 and 3.86 over a period of 2.7 days. It is a variable of a different type, classed as a slowly pulsating B star, a type of variable. It is around five times as massive as our Sun.
Lynx (constellation)
10 Ursae Majoris is the third-brightest star in Lynx. Originally in the neighbouring constellation Ursa Major, it became part of Lynx with the official establishment of the constellation's borders. Appearing to be of magnitude 3.97, a telescope reveals a yellow-white main sequence star of spectral type F4V of magnitude 4.11 and a star very similar to the Sun of spectral type G5V and magnitude 6.18. The two are 10.6 astronomical units (au) apart and orbit each other every 21.78 years. The system is 52.4 ± 0.6 light-years distant from Earth. Likewise 16 Lyncis was originally known as Psi Aurigae and conversely, 37, 39, 41 and 44 Lyncis became part of Ursa Major.
