It’s very unlikely to be the same mix of oxygen and nitrogen as the Earth’s atmosphere
though. Kepler-452b may not be exactly like the Earth, but it’s probably the most Earth-like planet that astronomers have found so far.
Why did Pluto stop being a planet?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because
it did not meet the three criteria the IAU uses to define a full-sized planet
. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

to travel using current technology.
Will Mars ever be habitable?
