Discovery of an incredibly Earth-like celestial body shocks the scientific community

1. Kepler-452b is known as “the second Earth”. The planet Kepler-452b orbits a Sun-like star and is located in the “habitable zone”, where conditions could allow liquid water to exist. Photo: Pinterest.

2. It is about 60% larger than Earth. With a diameter about 1.6 times larger than Earth, Kepler-452b belongs to the group of “Super-Earths” – rocky planets with larger masses but still similar conditions to Earth. Photo: Pinterest.

3. A year on Kepler-452b lasts 385 days. The planet takes nearly 385 days to complete one orbit around its host star – very close to Earth’s 365 days. Photo: Pinterest.

4. Its host star - Kepler-452 - is older than the Sun. The star Kepler-452 is about 10% larger than the Sun and is about 6 billion years old - about 1.5 billion years older than the Sun. Photo: Pinterest.

5. Kepler-452b's surface may have active volcanoes. With its greater gravity and possibly hot rocky core, the planet is believed to be geologically active. Photo: Pinterest.

6. The possibility of life remaining a mystery. Although located in the habitable zone, it is still unclear whether Kepler-452b has an atmosphere or water – two important factors for sustaining life. Photo: Pinterest.

7. It is the first planet discovered in the habitable zone orbiting a Sun-like star. Before Kepler-452b, planets in the habitable zone all orbited red dwarf stars – far different from our Sun. Photo: Pinterest.

8. Kepler-452b was discovered by the Kepler space telescope. NASA announced the discovery in July 2015, marking a major milestone in the search for “twin Earths” in the universe. Photo: Pinterest.
