What planet can support life besides Earth?

Potentially habitable planet Other planets of various sizes have been found in the habitable zones of their stars. However, Kepler-186f is the first alien planet this close to Earth in size found orbiting in that potentially life-supporting area of an extrasolar system, according to exoplanet scientists.

Why is Earth the only planet which support life?

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Is Earth the only planet with water?

Earth is the only known planet to have bodies of liquid water on its surface. ... Evidence points to water on other planets in our solar system. In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars.

Who discovered Earth?

Eratosthenes Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. He realized that if he knew the distance from Alexandria to Syene, he could easily calculate the circumference of Earth.

Is there a super Earth?

Super-Earths – a class of planets unlike any in our solar system – are more massive than Earth yet lighter than ice giants like Neptune and Uranus, and can be made of gas, rock or a combination of both. They are between twice the size of Earth and up to 10 times its mass.

What planet do astronomers believe there is life?

• Finding water on a planet is vitally important to proving that life exists there because it acts as a solvent in chemical reactions for carbon-based life. Another reason astronomers consider Mars as a likely location for life is because there is a good possibility that Mars is in the habitable zone.
