Kepler-452b is often referred to as Earth's cousin.
Kepler-452b, located in the constellation Cygnus, is considered an Earth-like exoplanet due to several factors, earning it the nickname "Earth's cousin." Here's a breakdown:
-
Size and Age: It's approximately 60% larger than Earth and significantly older, about 6 billion years old compared to Earth's 4.5 billion years.
-
Orbit: Its orbital period is 385 days, relatively close to Earth's 365 days.
-
Star: It orbits a star that is similar to our Sun but about 1.5 billion years older.
While Kepler-452b shares some similarities with Earth, important distinctions exist. The planet's larger size and age mean its surface conditions could be vastly different from Earth's. Whether it actually possesses an Earth-like environment suitable for life remains unknown.
