1. Астронет > HD70642: A Star with Similar Planets
... HD70642: A Star with Similar Planets . ... Credit: David A. Hardy, PPARC Explanation: Astronomers have discovered a planetary system more similar to our own Solar System than any known previously . The bright star HD70642 , visible with binoculars toward the constellation of Puppis , was already known to be a star like our Sun. Now a planet with twice Jupiter's mass has been discovered in a nearly circular orbit at approximately half the orbital distance of Jupiter. ...

3. Kepler 36b and c: Too Close for Comfort | Astronotes
... Planets . ... Earth Satellites . ... Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

4. ASP: A Good Definition of the Word "Planet": Mission Impossible?
... There has been a heated public discussion in the past few years about whether our ninth planet is really deserving of the name. Since Pluto orbits a star, and is much less luminous, it certainly satisfies the definition we have above. The problem is actually not with Pluto, but with a very large number of other bodies in our Solar System which also satisfy this definition, but which are not called planets. Perhaps the most notable of these is Ceres, the largest asteroid. ... Planet . ...

Next: J.G. Doyle, Research Astronomer Up: Research Previous: C.J. Butler, Research Astronomer Contents . Dr John Chambers has made detailed computer simulations of the origin and formation of the Earth and the inner planets. These build upon earlier work by Chambers and George Wetherill, of the Carnegie Institution of Washington, whose computer calculations had predicted that planets would tend to have elliptical orbits rather than the almost-circular ones we see in the Solar System. ...

12. Information on planets
... Given the observing time and frequency, task plplt plots the expected visibility function for a planet. You will most likely want to check this visibility function before observing and discovering that the planet is resolved out! NOTE that mfboot and plplt do not include the effect of the ATCA's primary beam - the planet is implicitly (and silently) assumed to be small compared with the primary beam. ... Information on using the ATCA to observe a planet is available on-line . ...
