These two planets – YSES-1 b and YSES-1 c – are considered the first multiplanetary system to be imaged directly around a Sun-like star. The star is a baby version of our Sun, just 17 million years old. The extreme youth of this system is a big part of the reason astronomers were able to capture direct images: the planets are so hot due to their recent formation that they still shine bright enough to be seen from our vantage point, even though they are hundreds of miles away. light years away.

Planets b and c are much farther from their star than Jupiter and Saturn are from the sun. Planet b is 160 times the Earth-Sun distance, planet c is about 320 times. Just for comparison purposes, Jupiter is 5 times the Earth-Sun distance, Saturn 10 times.
