Detecting Asteroids

[SeventhArchitect]

I already know that you can find Unknown Objects within the tracking station, BUT, I have no idea how to identify one of these in order to figure out it's orbit path. I've had a total of one asteroid come clsoe enough to Kerbin (it hit the planet, and I was depressed), but could not even figure out how to label it as an asteroid to plot it's course.

In the Tracking Station, if you select an unknown object, you should see the option to track it appear in the bottom left corner, where the "Fly / Abort" options normally are. The button should look like a blue radar dish.

Thank you. I launched a rocket for nothing.

No rocket launch is ever for nothing! It's a learning experience because now you know how to launch that particular rocket!

If you let me, I would like to ask another question about detecting asteroids.

I have noticed that after I track and catch or miss an identified asteroid, some new Unknown markers appear which can be further identified etc.

Are these other, already existing asteroids coming close to Kerbin, getting in range of the tracking station, or are they randomly generated after the existing ones are "used up"? To make it simple: can you run out of asteroids, or are they constantly regenerated?
