Will there be any serendipitous asteroid passes?

More importantly, will there be any such passes *after* the optical instruments are commissioned, several months after launch?

According to the latest tabulation, the closest approach to a known asteroid will be to the 2 km object 1999 JV26, which we pass on April 19th at a range of 1.3 million km. No asteroids will get bigger than 1.2 LORRI pixels.

Hmm... right on the inner edge of the belt.

I don't suppose NH will pass close enough to the the Lagrange point of Neptune to find any new Trojans?

NH will certainly be well off the orbital plane by the time it has covered so much of the leg between Jupiter and Pluto. Even if the trajectory were perfect in two dimensions, it'll be off in that one.

Just as an excercise, I wonder what magnitude of deltaVs would be required to (a) place NH on a course for a close flyby of JV26 and (b) restore the Jovian aimpoint after the flyby.

As for being above the plane, yes, but my mind was basically wandering along the lines of:

If there is a sphere around NH in the outer solar system in which Lorri would substantially exceed the resolution of ground-based telescopes, does this sphere ever include interesting regions of space such as the langrange points of any gas giant...

But no doubt the field of view isn't large enough to really work well in surveying large regions of emptiness.

According to Alan Stern in an interview on Planetary Radio, New Horizons will have a distant encounter with a Centaur in 2010.

Yes, I have to say that that was a good interview with Alan.

If I heard right, that "encounter" will be at a distance of 2.5 to 2.8 AU... but what's a couple hundred million miles between friends? Still that's a lot closer than we are right now.... biggrin.gif

Apparently they *are* hoping for some Neptunian trojans to pop into view in 2014!

The Asteroid belt falls roughly between 2.06 and 3.27 AU (see http://en.wikipedia.org/wiki/Asteroid_belt )
As for today New Horizons is 2.24 AU from the sun, so already entered the Asteroid belt some time ago.
Still 1.03 AU to go. Assuming the flight path makes an angle of 45° with the orbits (from New Horizons Current Position http://pluto.jhuapl.edu/mission/whereis_nh.php ) means New Horzions has to travel another 1.46 AU before it leaves the Asteroid belt.
This means, at an average speed of 28.64 km/sec, another 88 days inside the belt. Till august 22nd.
