How Far Away Is GJ 15 A b?
GJ 15 A b is one of the closest exoplanets to Earth, sitting just 11.6 light-years away — but even at that short distance, it would take tens of thousands of years to reach it. Find out what this super-Earth is like and how scientists discovered it.
TOI-5159 b: Getting to Know a Super-Earth
TOI-5159 b is a super-Earth located 180 light-years away, and it is bigger than our planet but smaller than Neptune. Scientists are working to figure out what this mysterious in-between world is made of — and the clues are pretty surprising!
Meet the TOI-1136 System: 6 Worlds Around One Star
About 276 light-years away, a star called TOI-1136 has six planets circling around it. One of them, TOI-1136 f, is almost four times wider than Earth — and scientists are using this crowded system to learn how planet families are built.
How Did We Find DMPP-6 c?
Scientists can't photograph DMPP-6 c, but they still proved it exists — 178 light-years away! Find out how a tiny starlight wobble and a cool trick called the Doppler effect helped astronomers uncover this mysterious world bigger than Earth but smaller than Neptune.
