Scientists discovered a rare planet larger than Jupiter orbiting a distant star once every 180 days. Known as NGTS-38 b, it is an exoplanet, meaning a world that orbits a star outside our solar system. These dimming events occur when a planet crosses in front of its star, a passage called a transit. According to the researchers, NGTS-38 b’s 180-day orbit is among the longest ever identified through the transit method. Because the planet takes around six months to complete each orbit, we only had a small number of opportunities to observe another transit.”
