SOLAR SYSTEM

Detailed explanation-1: -Planets that orbit around other stars are called exoplanets. Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit. So, astronomers use other ways to detect and study these distant planets.

Detailed explanation-2: -There are 5, 332 known exoplanets, or planets outside the Solar System that orbit a star, as of March 1, 2023; only a small fraction of these are located in the vicinity of the Solar System. Within 10 parsecs (32.6 light-years), there are 97 exoplanets listed as confirmed by the NASA Exoplanet Archive.

Detailed explanation-3: -Unlike the nearly circular orbits of the planets in our solar system, most exoplanets exhibit largely eccentric orbits. Most of the known exoplanets are gaseous, similar to the giant planets in our solar system, although some of the smaller exoplanets found show signs of rockier, terrestrial compositions.

Detailed explanation-4: -Astronomers report the discovery of two new exoplanets orbiting a bright sun-like star about 175 light years away. The newfound alien worlds, designated HIP 104045 b and HIP 104045 c, were classified as a Jupiter analog and a super Neptune planet, respectively.

Detailed explanation-5: -NASA exoplanet candidates (unconfirmed): 9, 432 These are the number of confirmed exoplanets and planetary systems by NASA, followed by the number of exoplanet candidates, which are discoveries that could be planets but are still unconfirmed by researchers.

Detailed explanation-6: -Planet-hosting stars are stars which host planets, therefore forming planetary systems. This article describes the correlations between stars’ characteristics and the characteristics of the planets that orbit them, and other connections between stars and their planets.
