Lessons Learned By One Old Timer Authors: Peter Bealo and Charlie McDonald Project Astro-Boston and the Amateur T elescope Makers of Boston I've been an amateur astronomer for over 25 years now, having been bitten by the bug the first time I viewed Saturn at a public star party. By the time I was 15 I too had begun participating in public star parties with my local astronomy club. ...

... Bad Astronomy . ... Bitesize Astronomy . ... If you thought our tour of the solar system ended with Neptune and Pluto, you are setting your sights way too low. The planets of the solar system mark time relatively close to the Sun compared to interstellar space. Pluto orbits the Sun at an average distance 40 times that of the Earth, yet the nearest star (the Alpha Centauri system) to the solar system is a mind-numbing 260,000 times the distance of the Earth to the Sun. ... 2008 Phil Plait. ...
