Can Kepler detect Earth sized planets?
These data were transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. Only planets whose orbits are seen edge-on from Earth could be detected….Kepler space telescope.

How long would it take to get to Kepler 20b?
This week astronomers announced planet Kepler 22-b lying 600 light years or 3,527,175,223,910,165 or three and a half quadrillion miles away and 2.4 times the size of the earth. Using a space shuttle, it would take 23.4 million years to reach it.
How big is Kepler 36B compared to Earth?
Kepler-36b, is a super-Earth that orbits a G-type star 1,533 light-years from Earth in 13.9 days. Its mass is about four times greater than Earth’s. Its companion planet, Kepler-36c is Neptune-sized with a mass more than seven times Earth’s; it takes 16.2 days to complete one orbit of the star, which is older and hotter than our Sun.
How big are the planets in the Kepler system?
The four companion planets, Kepler-186b, Kepler-186c, Kepler-186d, and Kepler-186e, whiz around their sun every four, seven, 13, and 22 days, respectively, making them too hot for life as we know it. These four inner planets all measure less than 1.5 times the size of Earth.
What did Kepler look for in the habitable zone?
Kepler was equipped to look for planets with size spans from one-half to twice the size of Earth (terrestrial planets) in the habitable zone of their stars where liquid water might exist in the natural state on the surface of the planet.
How often does Kepler 186f orbit its star?
Kepler-186f orbits its star once every 130 days and receives one-third the energy that Earth does from the sun, placing it near the outer edge of the habitable zone. If you could stand on the surface of Kepler-186f, the brightness of its star at high noon would appear as bright as our sun is about an hour before sunset on Earth.
