... Bad Astronomy . ... Bitesize Astronomy . ... The Nine Planets . ... The Sun stays at the center and the planets orbit it serenely, each in its place. ... Tiny Pluto, orbiting the Sun an average of nearly 40 times the Earth's orbital radius, has an odd orbit. Most planets orbit the Sun in nearly perfect circles, but Pluto's orbit is noticeably elliptical. ... The orbits of Pluto and Neptune have a coincidental timing to them: Pluto orbits the Sun twice for every three times Neptune does. ...

3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

... Officially the Chandra Deep Field - South, this picture represents the deepest ever x-ray image of the Universe. One million seconds of accumulated exposure time with the orbiting Chandra X-ray Observatory went in to its making. ... One of the brightest stars on the sky likely has planets. ... Amazingly detailed, this false-color x-ray image is centered on the galaxy Cygnus A. Recorded by the orbiting Chandra Observatory, Cygnus A is seen here as a spectacular high energy x-ray source. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

The apparent path of the Sun across the sky. ... The path of the Sun across the celestial sphere is very close to that of the planets and the moon. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...
