Exoplanet - IE - 17/01/23
Recently, the National Aeronautics and Space Administration’s (NASA) James Webb Space Telescope has discovered its first new exoplanet named- LHS 475 b.
->Key points of LHS 475 b?
It is roughly the same size as Earth, its diameter is 99% the same as Earth. It is a terrestrial, rocky planet about 41 light-years away from Earth in the constellation Octans. It differs from Earth in that it completes an orbit in just two days and is hundreds of degrees hotter than Earth. It is also closer to its star than any planet in our solar system is to the sun, although its star is less than half the temperature of the sun.
b. Significance: These first observational results from an Earth-size rocky planet open the door to many future possibilities for studying rocky planet atmospheres.
-Exoplanets are planets that orbit other stars and are beyond our solar system. The first confirmation of detection of exoplanets occurred in 1992. According to NASA, to date, more than 5,000 exoplanets have been discovered.
-Discovery: 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 exoplanets such as looking at the effects these planets have on the stars they orbit.
