Asteroids

[adambaldev]

Recently I have been looking at the new NASA chosen spacecraft: Lucy and Psyche. I was thinking that in Keerbal Space Program they should add asteroids with gravity and Asteroids that you are able to orbit. Are there any mods that add gravity to steroids?

if it has gravity than by definition it's not an asteroid is it? it's a celestial dwarf

Asteroids have gravity also. It is just extremely weak.

A standard sized asteroid wouldn't have enough gravity to affect a man or a space ship so it's a moot point really.

Relatively speaking, it wouldn't have gravity as far as you were concerned.

Gilly is probably the smallest moon in the game, with a miniscule amount of gravity. It's so light, you can escape Gilly with a kerbal's RCS pack on EVA. Anything less massive than that probably won't have any relevant gravitational force. Anything significantly less massive than that probably won't have any noticeable gravity at all.

Celestial bodies in KSP are somewhere around 10 times denser than they would be in real life, IIRC. So that means you can have asteroids and such be 10 times denser than they would be in real life, which makes them behave more like a planet while looking more like an asteroid. Even if you had had an incredibly massive asteroid, something truly gargantuan you would only see in a sci-fi film (but still nowhere near Gilly in terms of size), it still wouldn't have enough mass to exert any kind of noticeable gravity on you.

Please correct me if I'm wrong, I haven't played this game in awhile and I've just gotten back into it.

Actually, the celestial bodies in KSP are 10 times LESS dense, with engines about ten times less powerful to match.

For example, Kerbin is ten times smaller than Earth. It makes the game easier

You are right and wrong.

Kerbin is 10 times smaller than Earth, which is why it's also 10 times denser so that the numbers stay somewhat relevant.

The real reason why the asteroids dont have any gravity is because of how it works in game. Things either have gravity or can be affected by it, not both. So for asteroids, if they had SOIs, we wouldn't be able to move them or see them going all sorts of crazy when doing fly-bys. Extra fun fact: asteroids are basicly parts ingame, and there's a potatoroid part that appears in the editor sometimes

Ah, I see. My mistake. I need to think back to my grade 9 science classes.

There are a number of mods adding new planets and moons for you explore since they are large enough to have their own sphere of influence (read: gravity well).

There was a mod called Principia which simulated N-Body interactions between all bodies around Kerbol .. but I wouldn't recommend it for casual gaming, and I'm unsure if it ever supported asteroids.

Let's assume a huge 3,828t class E asteroid, a 150t spacecraft, and 200 meters between them.

If I've done my math right, on a circular orbit I believe our ship is traveling at 0.000112 m/s--a little too fine for our KSP speedometer.

Oh, on a related note, here is Scott Manley's video about an astronaut orbiting a space station.

It still has gravity, regardless of whether you think it wouldn't affect you or not, it is still there.

Everything with a non zero mass HAS gravity.
Now this gravity is (compared to the bigger bodies in the solar system) relativly unimportant, but at the beginning this gravity made them form up to what are now the bodies of our system.

You do understand the term "relatively speaking" yes?

Of course it still has gravity, but if it doesn't affect you in any meaningful way, it might as well not exist.

Especially in a video game where it would take extra work to implement and extra resources to run.

Relative or not, the person I was replying to said that if it had gravity it could not be an asteroid "by definition", that is false.

So quote him and not me then?
