K2-24b

K2-24b is a confirmed exoplanet orbiting the star K2-24, located approximately 610 light-years away in the constellation Taurus. It was discovered by the Kepler space telescope during its K2 mission, which was a repurposed mission following a malfunction that limited the original Kepler's field of view.

K2-24b is classified as a "hot Neptune" or a "warm Neptune" due to its relatively large size (roughly Neptune's size) and its proximity to its host star, resulting in a high equilibrium temperature. This close proximity translates to a short orbital period, which makes it easier to detect and study.

The planet was discovered using the transit method, which detects the slight dimming of a star's light as a planet passes in front of it. Data collected from these transits allows scientists to determine the planet's size and orbital period. Further observations and radial velocity measurements can then be used to estimate its mass and density, providing insights into its composition.

While details regarding the exact atmospheric composition of K2-24b are still being researched, studying planets like K2-24b contributes to a better understanding of planet formation and the diversity of exoplanets throughout the galaxy. It helps astronomers determine the prevalence of different types of planets and how they relate to the properties of their host stars.
