variable star in the constellation Pictor
Delta Pictoris, Latinized from δ Pictoris, is a binary star system in the southern constellation Pictor. It is visible to the naked with a combined apparent visual magnitude of 4.72. The system is located at a distance of approximately 1,300 light years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of ~31 km/s. It is a runaway star system that is generating a bow shock as it moves through the interstellar medium. Read more on Wikipedia.
Wikidata - #5 Omicron2 Cygni — --9,223,372,036,854,775,808 kg
Star in the constellation Cygnus
32 Cygni is a binary star system in the constellation of Cygnus. It has the Bayer designation Omicron2 Cyg, which is Latinized from ο2 Cyg and abbreviated ο3 Cyg. This is a 4th magnitude star, which can be seen with the naked eye under suitably dark skies. Parallax measurements give an estimated distance of 1,000 light-years (307 parsecs) from the Earth. However, Schröder et al. (2007) suggest the actual value, after correcting for Malmquist bias, may be closer to 1,174 light-years... Read more on Wikipedia.

star system in the constellation Taurus
Lambda Tauri, formally named Bibing, is a triple star system in the constellation Taurus. In 1848, the light from this system was found to vary periodically and it was determined to be an eclipsing binary system—the third such discovered. The components of this system have a combined apparent visual magnitude of +3.37 at its brightest, making it one of the brighter members of the constellation. Based upon parallax measurements from the Hipparcos mission, the distance to this system is... Read more on Wikipedia.

star in the constellation Perseus
1 Persei is an eclipsing binary star in the constellation Perseus. Its uneclipsed apparent magnitude is 5.49. The binary star consists of two B2 type main-sequence stars in a 25.9 day eccentric orbit. The stars are surrounded by a faint cloud of gas visible in mid-infrared, although whether they are the origin of the gas or simply passing through it is unclear. Read more on Wikipedia.
