Did you know that Kepler-90 is a star very similar to our Sun, but its eight planets are grouped in the distance between Earth and the Sun? Watch this reel to explore a unique cosmic setup!

1️⃣ Fast orbits: The innermost planet, Kepler-90b, orbits the star every 7 days — compare that to Mercury's 88 days!

2️⃣ Scorching heat: Kepler-90i has an average temperature of 436°C – too hot for any life as we know it.

3️⃣ Planetary Migration: These planets are thought to have originally formed further away from each other and migrated to their current tight orbits. How and why? We're still finding out!

Kepler-90's compact solar system challenges our understanding of planet formation and migration. What do you think this star system looked like millions of years ago?
