Earth Like Planets In Our Solar System

Venus venus thick atmosphere makes it the hottest planet in our solar system.

Earth like planets in our solar system. Nasa just found a solar system with 7 earth like planets. Yet earth remains a standout and so far one of a kind. The energy output from dwarf stars like trappist 1 is much weaker than that of our sun. Earth the only planet in our solar system with liquid water on the surface.

Mars mars was a wet and warm planet billions of years ago. The thousands of exoplanetary star systems discovered so far are profoundly different from our solar. Planets would need to be in far closer. Most of the potentially earth like planets spotted by scientists have been in residence around red dwarf.

Other solar systems could cram in as many as seven earth like planets. Koi 456 04 is bigger than earth but still less than twice the size of our own planet. The hunt to find exoplanets like our own has only just begun. Its 267 day orbit however puts kepler 62f squarely within the habitable zone.

In 1992 the first planets outside our solar system were discovered via a pulsar 2300 light years away that signalled at slightly odd. We might want to blame jupiter for the lack of other habitable planets around our own sun. The kepler 62 system. Of the thousands of exoplanets planets around other stars confirmed by our increasingly powerful telescopes and despite extensive probing of the solar system ours is still the only planet known to host life.

Before the scientific search for and study of extrasolar planets the possibility was argued through philosophy and science fiction the mediocrity principle suggests that planets like earth should be common in the universe while the rare earth hypothesis suggests that they are extremely rare.
