NASA Found a Planet That’s Mostly Made of Iron
Astronomers studying
NASA data discovered an unusual exoplanet that may be composed mostly of iron.
The planet, GJ 367 b,
is located about 31 light-years away from Earth. Scientists believe it has an extremely dense
structure — similar to a planet's iron core, but making up most of the
entire world.
This discovery was
made using NASA’s Transiting Exoplanet Survey Satellite, which searches for
planets orbiting distant stars.
What makes this
planet special?
• It’s about 80–90%
iron
• Much denser than
Earth
• Orbits its star
within eight hours. The exposed core of a planet may have lost its outer layers
as a result of intense radiation from its nearby star, according to scientists.
In other words, this world could be what remains after a planet was stripped
down to its metallic heart.
