The Planet That Falls Into Its Star

Some planets orbit extremely close to their stars and can experience powerful gravitational effects. Over long periods, interactions between a planet and its star may cause the planet’s orbit to gradually change. In certain systems, a planet could slowly move inward and eventually face destruction as it approaches the star. Extreme heat can vaporize the planet’s atmosphere and surface, while intense gravity and stellar forces can further damage the world. Astronomers have observed evidence of stars consuming planetary material, giving scientists clues about how planetary systems evolve and eventually change. These dramatic events can happen over enormous timescales, often millions or billions of years. Studying planets near the end of their lives helps researchers understand the relationship between stars and their planets. It also provides a glimpse into possible futures for some planetary systems as their stars grow older and become more powerful. #PlanetDeathExoplanetsStarAndPlanetSpaceFactsAstronomyDeepSpacePlanetaryScienceUniverseAstrophysicsSpaceDiscovery
