What are the most Earth-like worlds we''ve found?

What is an Earth-like world? Though there are some basic requirements for a world to be considered Earth-like, overall, it''s difficult to narrow down a definition.

Compared to Other Planetary Systems, Our Solar System Is

Our Solar System may be home, but researchers are now discovering that it''s not really much like the other kids. According to a survey of 909 planets orbiting 355 stars, our home planetary system is a little on the dishevelled side - and others are a lot more orderly.

Life in the Universe: What are the Odds?

In our solar system, Earth sits comfortably inside the Sun''s habitable zone. Broiling planet Venus is within the inner edge, while refrigerated Mars is near the outer boundary. Determine the distance of an exoplanet from the star itself, as well as the star''s size and energy output, and you can estimate whether the planet falls within the habitable zone.

Planets Around Other Stars

What are exoplanets? Throughout recorded history and perhaps before, we have wondered about the possible existence of other worlds, like or unlike our own. The earliest understanding of the solar system showed us that there were indeed other worlds in orbit about our Sun, and steadily growing understanding of their natures shows that all are []

Distant Solar System Found That Is Very Similar To Ours

If the system were aligned like our solar system, with no orbital tilt, it would provide evidence that only hot Jupiter systems are misaligned, formed as a result of planetary scattering." In order to resolve the puzzle, Sanchis-Ojeda looked through data from the Kepler space telescope, an instrument that monitors 150,000 stars for signs of distant planets.
