Distant extrasolar planets are called exoplanets. Scientists have uncovered a method to measure their magnetic field. It’s crucial to understand the magnetic fields of planets to understand their interface with other cosmic objects. Exoplanets are planets that are found outside our solar system and gravitate around a star.
Researchers found the method by watching and calculating a specific exoplanet called HD209458, located 50 light years from the solar system It is located in the constellation Pegasus.
