Astronomers find a “forbidden planet” orbiting an impossibly tiny star

Survival would be your primary concern, but if you can make it, if you can hold fast until you reach another star, you'll be a witness to wonders no other human has ever beheld up close.

This isn't the first time we've found a gas giant around a red dwarf star, but it is the first time we've found one around a star so small. TOI-5205's mass is estimated to be only about four times that of Jupiter. For comparison, the Sun is roughly a thousand times more massive than Jupiter.

12 New Moons Have Been Found Orbiting Jupiter, Say Scientists

Jupiter now officially has 92 moons after astronomers observed 12 new natural satellites orbiting the solar system's largest planet.

Nine of the new moons orbit "backwards" relative to the inner moons, evidence that they are objects captured by Jupiter's gravity.

Marauding Moons Spell Disaster for Some Planets - Eos

Roughly half of all stars have planets orbiting them, scientists currently believe. And surely many have moons, too, if our own solar system is any indication (only Mercury and Venus lack them).

Astronomers think that solar systems are born from spinning clouds of gas and dust. Over time, that primordial material coalesces into larger bodies, which go on to collide with one another, forming planets and moons.

Planets Remarkably Similar to Jupiter And Neptune Found Orbiting a Sun-Like Star

An intriguing pair of gas giants has been found orbiting a star so similar to the Sun it could practically be its twin, and it could teach us a thing or two about solar systems like ours.

This discovery, submitted to the Monthly Notices of the Royal Astronomical Society and available on preprint server arXiv , is helping us understand the variety of systems that can orbit Sun-like stars, in the hopes of finally finding a second Earth.
