Astronomers Discover Rare Free-Floating Planet 10,000 Light-Years Away

• Astronomers confirmed a rare free-floating planet, not bound to any star, 10,000 light-years away.
• Detected via gravitational microlensing, a brief brightening of background starlight.
• The short microlensing event indicated a planetary-mass object similar to Earth's mass.
• Its motion within the Galactic disc suggests it was likely ejected from a young planetary system.
• This discovery implies rogue planets may be common, reshaping understanding of galaxy evolution.

Why It Matters: Rare free-floating planet discovery confirms theoretical predictions, suggesting millions exist in Milky Way.
