## 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.
## Key takeaway

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.
