Zeta Reticuli is a unique system in the solar neighborhood -- a wide physically associated pair of stars almost exactly like the Sun. After searching through a list of stars selected from the Gliese catalog on the basis of life criteria, only one other pair within a separation of even light-years could be found.

Observations of stars, most notably S2 that orbit around Sagittarius A have been used to show the presence of a supermassive black hole at that location. S2's highly eccentric orbit and proximity to Sagittarius A has been instrumental for scientists use in determining the location and mass of Sagittarius A. At it's closest to Sagittarius A* S2.

Nu Orionis (ν Orionis) is a binary star system in the northeastern part of the constellation should not be confused with the variable star NU Orionis.

Nu Orionis has an apparent visual magnitude ofwhich is bright enough to be seen with the naked eye. Based upon an annual parallax shift of arcseconds, the distance to this system is roughly light llation: Orion.

In two cases (Theta1 Ori E and Spectroscopic Orbit of nu Orionis. book J), enough photometric and spectroscopic data exist to attempt an orbit solution and derive the system parameters.

Xi Orionis (ξ Orionis) is a binary star system in the northeastern part of the constellation of Orion, well above the red giant star, Betelgeuse in the sky. It lies next to another blue main-sequence star, Nu Orionis which is somewhat closer at light apparent visual magnitude of Xi Orionis iswhich is bright enough to be seen with the naked llation: Orion.

The summation of the whole matter is that the orbit in which a body moves around the sun, or past the sun, depends upon its velocity and if this velocity and the direction of the motion at any one point in the orbit are known the whole orbit is determined by them, and the position of the planet in its orbit for past as well as future times can.

LATTER, G. OGILVIE, H. REIN Abstract This chapter explores the physics shared by planetary rings and the various disks that populate the Universe.

It begins with an observational overview, ranging from protoplanetary disks to spiral galaxies, and then compares and contrasts these astrophysical disks with the rings of the Solar Size: 3MB. No eye can fail to note her, and as the nearest and most beautiful of the Earth's sisters it would seem that everybody should be as familiar with her appearance as with the face of a friend.

But the popular ignorance of Venus, and the other members of the planetary family to which our mother, the Earth, belongs, is only an index of the denser ignorance concerning the stars—the brothers of.

A solar binary of the Sun and Jupiter may serve to establish an upper limit for interstellar cometary capture. The basic problem even with a passage through a molecular cloud of some 10 million years is the low relative velocity (~ km s-1) required between the solar system and the cometary of the captured bodies may localize in the Oort cloud, while others localize near the Sun.
