From the reported value dtd AU = 15 ± 4 (m/cy), we have obtained the required value for the variation of rotational period of the Sun is about 3 (ms/cy), if we assume that eight planets in the solar system experience the same orbital expansion rate. This value is sufficiently small, and at present i ...

... The other half have very eccentric orbits; this means that, throughout their years, they come very close to and very far from their parent star. This will create wide temperature swings, and for any life like Earth's, this would make survival quite difficult, if not impossible. ...

Why Pluto Is Not a Planet Anymore or How Astronomical Objects Get

A minor planet is an astronomical object in direct orbit around the Sun that is neither a dominant planet nor originally classified as a comet. The term minor planet ha ...

Kepler`s Search for Exoplanets
... Here we’ve marked stars with confirmed exoplanets. There are over nearly 2000 confirmed exoplanets [update as needed], and we’re still just getting started! Results from Kepler indicate that it’s likely every star we see in the night sky has planets. And it’s just a matter of time before we find ano ...

WASP-24b: A New Transiting Close-in Hot Jupiter
... blended in the SuperWASP imaging, N1 is ∼6.7 mag fainter in V. N1 will have had minimal effect on the WASP transit photometry because even at its brightest it is below the limit of detectability in the SW exposures. N1 is clearly separated from WASP-24 in the follow-up photometry, as shown by Figure ...
