Some planets may be better for life than Earth
Scientists find 24 exoplanets with conditions more suitable for life than Earth.
In brief
Scientists find 24 exoplanets with conditions more suitable for life than Earth. Researchers identified 24 exoplanets outside our solar system that may have conditions more suitable for life than Earth, including older, slightly larger, warmer planets with more moisture.

Superhabitable planets
Scientists identified 24 exoplanets outside our solar system that may have conditions more suitable for life than Earth.
“Earth is not necessarily the best planet in the universe.”
Conditions for life
These planets could be older, slightly larger, warmer, and wetter than Earth with more moisture for life to thrive.
Star types matter
Planets orbiting stars with longer lifespans than our sun could develop more complex life over time.
K dwarf stars
K dwarf stars have lifespans of 20 to 70 billion years, allowing planets to develop complex life more fully.
Age sweet spot
The ideal age for life is between 5 and 8 billion years, balancing geothermal heat and protective magnetic fields.
Size and mass
A planet 10% larger than Earth would have more habitable land, and 1.5 times Earth's mass would retain heat longer.
Water and warmth
Slightly warmer temperatures and more moisture could boost biodiversity, similar to Earth's tropical rainforests.
One candidate
One planet has four critical superhabitable characteristics, making it potentially better for life than Earth.
The main idea
Researchers identified 24 exoplanets outside our solar system that may have conditions more suitable for life than Earth, including older, slightly larger, warmer planets with more moisture.
