Default 45 new TNOs

Hum,
45 new multiple-opposition Trans-Neptunian objects have been listed on the M.P.E.C. website...

See the result of a four year search by Canadian and French researchers using the Canada France Hawaii Telescope...

With luck we'll find a couple of really nice ones close to the post-Pluto trajectory of New Horizons.

Hum,

"Astronomers have found 45 previously unknown bodies of rock and ice orbiting beyond Neptune in the Kuiper Belt. They range from about 50 to 500 kilometres wide.
The announcement is probably a record for the most new solar system objects reported simultaneously, increasing the number of distant objects with well defined orbits by nearly 10%.
But its real importance will be in measuring the distribution of distant objects well enough to test theories of how the outer solar system evolved."

Good thing it was not a Michael Brown announcement:
45 New Planets Discovered!
That would have been a little too much at once!

Oh, I don't know. In some ways, that would paint a better "mind picture" of the solar system than the mid-20th century picture that most people are used to. There is just so much detail to our solar system . . .

In Discover this month, it seems Mike Brown has shifted his position back to "there's eight planets."

Averaging over the time period since 1992QB1 was discovered, about 70 TNOs have been discovered a year. Extrapolating forward, we may have as many as ~600 more by the the time NH reaches Pluto, and that's barring any new advances in CCD sensitivity or larger telescopes.

Which is a little odd, to my way of thinking - Pluto's planetary credentials improved significantly in my eyes with the discovery of its second and third moons.

As did asteroid Sylvia when its moons "Romulus" and "Remus" were detected? Maybe, some day we will end up with Pluto and Sylvia being planets, while Mercury and Venus are considered large asteroids...

The nearly Pluto sized oddball, 2003 EL61, has also two satellites.

Pan-STARRS and the Discovery Channel Telescope may change this.
