Star

Gliese 86, more often abbreviated Gl 86, is a K-type dwarf star approximately 35 light-years away in the constellation of Eridanus. It has been confirmed that a white dwarf orbits the primary star. As of 2000, an extrasolar planet has been confirmed to be orbiting the star.

HD 38529 (also known as HR 1988) is a binary star approximately 138 light-years away in the constellation of Orion.

HD 164922 is a seventh magnitude star in the constellation of Hercules. It is an orange dwarf with a spectral type K0V. To view it, binoculars or a telescope are necessary, as it is too faint to be visible to the naked eye. It is 71.5 light years distant from the Earth. At an age of 13.4 billion years, it will soon evolve away from the main-sequence and expand to become a red giant. Its metallicity is nearly 50% more than the Sun.

Solar-Type, Solar Analog, and Solar Twin stars are those stars that are particularly similar to the Sun, with solar twin being more similar than solar analog, and solar-type being less similar than solar analog. Observations of these stars are important for understanding better the properties of our own Sun in relation to other stars and the habitability of planet.

Pollux, also catalogued as Beta Geminorum (β Gem / β Geminorum), is an orange giant star approximately 34 light-years from Earth in the constellation of Gemini (the Twins). Pollux is the brightest star in the constellation, brighter than Castor (Alpha Geminorum). As of 2006, Pollux was confirmed to have an extrasolar planet orbiting it.
