Not counting comets and Jupiter Trojans there are currently 40 minor objects between 5 and 10 AU from the sun (by my calculations at least)

Next object New Horizons will pass (in current distance from the sun) is 2000 GM137, a centaur at 8.06 AU

It will not have been tracked since launch - it would only be a best guess - you may find some info regarding it in the annals of the NH website, it was mentioned in the past.

UPDATE! On 11/15/2007, at 11:04:35 UTC, the NH spacecraft reached 1200 million km from the sun. The spacecraft's distance from Earth, by comparison, is nearly 1.332 billion km. NH is now only 3.514 billion km from Pluto and traveling at a rate of 19.463 km/s. Later!

I expect an update at only 3.14159 billion km from Pluto, as that figure will obviously be of cosmic importance as well!

Well, NH has travelled 1.5 Billion KM (well 1.499 as this post). and she is almost 2 now

And in the "are we there yet" spirit, I note that the current-position chart has be rescaled again, so the outer boundary is now Saturn's orbit, not Jupiter's.

Amazing how fast we're reaching the orbit of Saturn -- after just 2.5 years. Amazing how that'll only be half-way to the orbit of Uranus. And 1/3 of the way to Neptune's.

As I see that New Horizons is decreasing its speed toward Pluto. How fast will NH be traveling past Pluto?

I think its about 12,000 mph when the Pluto flyby occurs.

I meant to say 12 km/s, so I was fairly close. 14 it is then. NH will fly by Pluto at 14 km/s. huh.gif
