Other variations in the motion were accounted for by offsetting the centres of the deferent for each planet from Earth by a short distance. By choosing the combination of speeds and distances appropriately, Ptolemy was able to predict the motions of the planets with considerable accuracy. His ...
the universe is a system of magnetic bodies in which, with corresponding like poles repelling and unlike poles attracting, the rotating Sun sweeps the planets around. The solar force,attenuatinginversely with distance in the planes of theorbits, was the major physical principle that guided Kepler’...
Kepler-62 in the constellation Lyra, and is about 1,200 light-years from Earth. 62e is 1.61 times Earth’s size, circles the star in 122.4 (Earth) days. 62f is 1.4 times the size of Earth, and orbits its star in 267.3 days. Previously, the smallest planet with known radius inside ...

Though inactive, Kepler will continue in its Earth-trailing orbit around the sun, passing through Earth's neighborhood (at a safe distance) in 2060 and again in 2117. Kepler's role as the leading exoplanet-hunting space telescope was taken over by the Transiting Exoplanet Survey Satellite (TE...
Considering the effects of stellar effective temperature on habitable zone, we give the distance equations on the inside and the outside boundary of binary's habitable zone. Using the numerical methods, we obtain the habitable zone of the Kepler-47 binary system. The average distances on the ...
