Astronomers with the Gemini Observatory say they may have captured the first picture of a planet orbiting another Sun-like star. The star, 1RXS
J160929.1-210524, is about 500 light-years away, and is much younger the Sun.

This object is the parent body of the Geminid meteor stream, the concentration of meteoroids responsible for the annual Geminid meteor shower seen on Earth each December.

As such, it is intimately associated with legends concerning the constellation of Gemini, which it is in contact with. Firstly, with Gemini, it may form the origin of the myth of Castor and Polydeuces, concerning cattle raiding.

It was followed (in the US) by "Gemini" whose two-man capsules were orbited by the more powerful Titan rocket. Then came the three-man "Apollo" missions, first flying around the Moon and then landing on its surface, on July 20, 1969.

During one month, Mars would be seen in Gemini and then after several weeks it would gradually move over to Cancer.

After the Mercury project, Project Gemini was launched to conduct experiments and work out issues relating to a moon mission. The first Gemini flight with astronauts on board, Gemini 3, was flown by Gus Grissom and John Young on March 23, 1965.
