Gliese 667C F

The two brightest stars in this system, GJ 667 A and GJ 667 B, are orbiting each other at an average angular separation of 1. 81 arcseconds with a high eccentricity of 0. 58. At the estimated distance of this system, this is equivalent to a physical separation of about 12. 6 AU, or nearly 13 times the separation of the Earth from the Sun. Their eccentric orbit brings the pair as close as about 5 AU to each other, or as distant as 20 AU, corresponding to an eccentricity of 0. 6. [note 1] This orbit takes approximately 42. 15 years to complete and the orbital plane is inclined at an angle of 128° to the line of sight from the Earth. The third star, GJ 667 C, orbits the GJ 667 AB pair at an angular separation of about 30″, which equates to a minimum separation of 230 AU.



A moon is defined as a natural satellite in orbit around another body that, in turn, is in orbit around its Star. The moon is kept in its position by both its own gravity, as well as its host's gravitational grip. Some planets have many moons, some have only a small number, and still others have none at all. Several asteroids inhabiting our Solar System are circled by very small moons, and some dwarf planets--such as Pluto--also host moons. The bottom line is that these two forces of Mother Nature have an amazing impact on the feeding activity of fish and using this information to your advantage will make you a more successful angler. Take a few minutes and learn some of the simple rules relating to the weather, the moon, and fishing as soon as you can if you want to catch more and bigger fish. HST's detection of a site, which appears to show persistent, intermittent plume activity on Europa, provides a promising target for the Europa mission to investigate. Equipped with its new and sophisticated suite of science instruments, the mission can detect whatever may potentially be swimming around in the hidden global ocean sloshing around beneath its secretive crust of ice.
