Did I forget something?

14 years ... but not to scale.

All visited Asteroids:

smile.gif nice resume!

Cool! smile.gif

I wouldn't mind seeing a scale version, though - it would be interesting to see the relative sizes.

Cool! Do a scale chart!

Here are some I found on the internet.

It might be good to include Phobos, Deimos, and the four comet nulcei.

Probably be useful to put the long-axis dimensions in km for each on the pic, and the closeup-image of Dactyl.. good job!

And for one of these asteroids... here's a shaded relief map of Eros which I have just put together from the NEAR laser ranging instrument dataset... in cylindrical projection. This particular processing version has the effect of flattening the largest craters, so I'll work on that.

(PS - edit a few hours later - I have fixed the map and changed the old one for the improved version, so this one is OK)

Don't forget this encounter...

Or Calypso and Telesto, two recently encountered Saturnian satellites in this size range.

I am really stretching my memory here, but it seems I read (maybe 20 years ago) that Vega 1 (or was it 2?) might have an asteroid encounter after the Halley's Comet encounter.

Aphoris? Adonis? Arachnis? (heck to get old!)

Did it ever happen? Did the probes get shutdown before it happened?

btw, is Giotto still working?

To quote:

"Since both VEGA craft were still functioning after their Halley
encounters, Soviet scientists considered an option to send the
probes to other celestial objects. One prime target was the near-
Earth planetoid 2101 Adonis, which VEGA 2 could pass at a distance
of six million kilometers (3.6 million miles). Sadly, the Soviets
had to back out on the opportunity to become the first nation to fly
a spacecraft past a planetoid when it was discovered that there was
not enough maneuvering fuel in the probe to reach Adonis as planned.
VEGA 1 and 2 were quietly shut down in early 1987."

I believe Giotto is in hibernation mode. It may be awoken again at some point.
It will make a close flyby of Earth in 2016.

Thanx for the update.

Too bad we can't top off the tanks for 'em.

btw:

Appreciate all the nice asteroid pictures!

I don't recall seeing any asteroids in any movie (sorry Mr. Lucas) that look like those.

Anyone recall a film with great looking rocks?

Well, 2001 had some nice asteroids...

Too knobbley and too shiny and not cratered enough as I recall.

I suppose I should try to find a still . . . .

Probably about time that Itokawa was added to the montage above. Incredible to think it is smaller than Dactyl!
