Now, data from the James Webb Space Telescope has revealed another intriguing feature of the planet known as HD 189733b: It smells like rotten eggs. Located only 64 light-years from Earth, HD 189733b is the nearest hot Jupiter that astronomers can study as the planet passes in front of its star. HD 189733b only takes about two Earth days to complete a single orbit around its star, Fu said. Webb’s data also showed levels of heavy metals on HD 189733b that are similar to those found on Jupiter. “HD 189733b is a benchmark planet, but it represents just a single data point,” Fu said.
