There are countless solar systems in the universe, with each system consisting of a star or multiple stars and their orbiting planets and other celestial bodies. While our own solar system is named after our star, the Sun, other solar systems are given unique names based on the star they revolve around.

One of the most well-known solar systems outside of our own is the TRAPPIST-1 system. It is named after the star TRAPPIST-1, which is a small, faint red dwarf star located about 39 light-years away from Earth in the constellation Aquarius. This system gained significant attention when scientists discovered that it has seven Earth-sized planets orbiting it, three of which are located in the star's habitable zone where liquid water could potentially exist.

Another notable solar system is the Kepler-90 system, which is named after the star Kepler-90. This system is located approximately 2,545 light-years away from Earth in the constellation Draco. Kepler-90 gained prominence when astronomers discovered that it has eight planets, similar to our own solar system. The discovery of this eighth planet, known as Kepler-90i, made the Kepler-90 system the first known solar system outside of our own to have as many planets as ours.

In addition to TRAPPIST-1 and Kepler-90, there are numerous other solar systems that have been discovered and named by scientists. These include the Proxima Centauri system, the Wolf 1061 system, the Gliese 581 system, the HD 10180 system, and many more. Each of these systems offers unique insights into the diversity and complexity of planetary systems in the universe.

It is worth noting that the names of solar systems are typically based on the star they revolve around, rather than a specific naming convention. As our understanding of the universe expands and new solar systems are discovered, astronomers will continue to assign names to these systems based on their respective stars.
