HD 136418 b, also known as Awasis, is a planet that orbits a star outside our solar system. These types of planets are called exoplanets. Awasis orbits a star named HD 136418, which is a G-type star. This means its star is very similar to our own Sun in temperature.
This exoplanet is about 320 light years away from Earth. It is located in the constellation called Boötes. One special thing about Awasis is its orbit. It stays within what scientists call the habitable zone. This is the area around a star where temperatures might be just right for liquid water to exist on a planet's surface. Liquid water is important for life as we know it.
Discovering Awasis
Scientists found HD 136418 b on March 17, 2010. They used a method called Doppler spectroscopy. This method helps astronomers find planets by looking for tiny wobbles in a star's movement. These wobbles are caused by the gravity of an orbiting planet pulling on the star.
Naming the Planet
In 2019, the International Astronomical Union (IAU) held a contest called NameExoWorlds. Countries around the world could suggest names for exoplanets and their stars. Canada chose the name "Awasis" for HD 136418 b. "Awasis" means "child" in the Cree language.
The star that Awasis orbits, HD 136418, also received a new name in the same contest. It was named "Nikawiy," which means "mother" in the Cree language. This naming connects the planet and its star with a special meaning from the Cree culture.
