Could TRAPPIST-1’s Seven Worlds Host Moons?

Scientists have discovered that moons could theoretically orbit all seven planets in the TRAPPIST-1 system despite the complex gravitational environment. Using computer simulations, a team of researchers have mapped stable zones where satellites could survive around each planet. They found that moons can remain stable up to about 40-45% of each planet’s sphere of gravitational influence. The neighbouring planets squeeze these stable zones slightly inward compared to isolated planets, but t
