  70 Virginis - Wikipedia, the free encyclopedia
70 Virginis (also designated HD 217014 and SAO 090896, HR 5072) is a main sequence star in the constellation Virgo.
It has a confirmed extrasolar planet 70 Virginis b (initially named Goldilocks), at least 6.6 Jupiter masses in size, located about 0.5AU from the star.
In 1996 Geoffrey Marcy used the then known, and uncertain, parallax of 0.112 to derive a distance from Earth of 8.9 parsecs (29 light years), and also derived the effective temperature of the planet to be about 90 degrees Celsius.

The stars that have been catapulted to fame are 70 Virginis and 47 Ursae Majoris, two otherwise innocuous fifth-magnitude stars near the limit of naked-eye visibility in the constellations Virgo and Ursa Major.
The discovery of the 70 Virginis and 47 Ursae Majoris planets is the result of a project begun in 1987 by San Francisco State University and the University of California, Berkeley.
Marcy suggests that the atmosphere of the planetary companion to 70 Virginis has a "surface" temperature of 85 degrees C, which is warm enough for liquid water to exist.

The star 70 Virginis is an extrasolar planetary system with one confirmed planet 6.6 times the mass of Jupiter.
Because of the presence of a galaxy cluster (consequently called the Virgo cluster) within its borders 5° to 10° west of Vindemiatrix (ε Vir), this constellation is especially rich in galaxies.

 Extrasolar Visions - 70 Virginis b
70 Virginis b was one of two planets announced by Marcy and Butler in early 1996.
Not as brutally hot as 51 Pegasi b and not as cold as 47 Ursae Majoris b, 70 Virginis b was believed to exist in a more temperate orbit that might have allowed liquid water to form on its moons.
Lost in the light of 70 Virginis itself, this glow would only be visible on the night side of the planet.

 Extrasolar Visions - 70 Virginis b
70 Vir b is massive enough to be neither tidally locked by its star nor have any significant limits placed on the mass of its moons.
70 Virginis b is too close to its star for liquid water to be stable on its moons.
Before the thin blue crescent of 70 Virginis b hangs a small moon so severely heated by tidal stress that lakes of molten lava glow on its surface.

The planetary companion to 70 Vir is up to 6.5 times as heavy as Jupiter and has an orbit that is only 117 days in duration.
The companion to 70 Virginis has a semimajor axis of 2 A.U. Marcy puts the temperature of its atmosphere at 82 degrees Celsius, which is warm enough for liquid water to exist.

 70 Virginis
70 Virginis is a yellow-orange main sequence dwarf star of spectral and luminosity type G5 Va, but has been previously classified from G2.5 to G4.
The star has about 1.10 percent of Sol's mass (70 Virginis at exoplanets.org), 2.0 to 2.5 times its diameter (Henry et al, 1997), and 2.9 times its luminosity.
It moves around 70 Virginis at an average distance of only 0.48 AUs (a semi-major axis around Mercury's orbital distance) in a highly elliptical orbit (e=0.40) that takes almost 167 days to complete.

If you would like to rewrite it in a coherent paragraph or several, beginning with an explanation of what "70 Virginis" is, that would be grand.
Now, it seems to me that anyone who gets as far as "70 Virginis" in a wiki is going to know that this is a stellar designation, and if someone else wants to put double brackets around such jargon as "parallax" that might not be in a tiny dictionary, that's one thing.

 Science News: Two extrasolar planets may hold water - Science News of the Week
Thus, 70 Virginis is unlikely to possess an array of orbiting bodies akin to our solar system, notes David C. Black, director of the Lunar and Planetary Institute in Houston.
Butler speculates that the body orbiting 70 Virginis may belong to a new class of objects-superplanets, which have a mass greater than that any planet in our solar system and less than that of failed stars, known as brown dwarfs.
In fact, Boss maintains, the object circling 70 Virginis is undoubtedly the lowest-mass brown dwarf ever found, and the object circling 47 Ursae Majoris is the most massive planet known.

Unlike the smaller, Jupiter-sized planets orbiting stars like Rho 1 Cancri and 51 Pegasi, the object orbiting 70 Virginis is very large (minimum mass 7.4 times the mass of Jupiter).
In fact, the mass of 70 Virginis B is close to the theoretical limit for a brown dwarf, a type of object intermediate in mass between true planets and true stars.

Professor Geoffrey Marcy of San Francisco State University announced the discovery of a planet orbiting 70 Virginis (in the constellation Virgo) and one orbiting 47 Ursa Majoris (in the Big Dipper).
Marcy believes that the planet orbiting 70 Virginis is about nine times larger than Jupiter and orbits its host in 116 days.
