Hitting planets with other objects should not destroy units in space.

No, immersion is immersion. Jesus.

Cannons can't insert their ammo into orbits that don't intersect with the ground. Thus everything will fall back down after crossing the orbit max 2 times. It would not be a long term hazard.

When we will have limited destruction impacts it would make sense to have the area of effect on the orbital layer be substantially smaller than in the layers below.

In space noone can hear you scream as there is nothing to relay sound. Thus satellites are safe from shockwaves as they are outside the athmosphere.

So, basically, shouldn't the planet itself be unreachable? If nothing can leave it, nothing should be able to land on it.

But of course, game-play first.

I think that spacecrafts in gravity well should be spared (but can be damaged above impact area), it makes a lot of sense game-play wise.

Also I think that moons and asteroids (smaller than moons, not in game yet) shouldn't provide binary effect on the planet and take into account size of both bodies to plot damage areas (imminent death zone, 80% dmg, 40% dmg, etc.).

Yes, but satellites are not safe from mass, which is what the shockwave on your planet has just done. It ejects a huge amount of mass into the space, which is retained by Earth's gravity well, just at a further distance from centre that it previously was.

Kiwi is right on that. It is no way the initial force from the impact of the two bodies colliding isn't what destroys the orbiting objects. In fact I didn't mention a shockwave in my post (I don't know what you were referring to), but there would be enough debris, even simply thrown into orbit (doesn't even have to move that quickly) would destroy anything in that planets orbit. \

And as far as "orbit max 2 times" that isn't true at all. Many rings and even moons around orbital bodies are formed by bodies smashing together and getting caught in stable gravity wells. And taking into account the ratios of planet sizes are being smashes into each other (many times being equal in size or bigger) the amount of debris that would be flung into the atmosphere would shred anything in low orbit relatively quickly, and possibly form a ring around the planet that could stay there indefinite (to the end of the planets life).

Now as far as it being real. This is more just an excuse for the current implementation of the orbital impacts. As they currently destroy the entire planet. But I even if the impact destroys only a portion of the ground forces on a planet, I still believe that it should still destroy all the orbital from a gameplay perspective. Things such as radar being able to have a visual on a planet even after a planet/moon/asteroid impact wouldn't be that clever as player could then lob nukes at the remaining areas. I rather see an implementation that if you have direct visual all the intel on the planet is destroyed to help motivate more/better scouting.

And yes, the debris would make it impossible for anything to get back into orbit. But the entire event can just be a simple visual and fade away. Nothing in this game is 100% accurate. But it gets many broad ideas across pretty well. Why not this one?

I don't see why everything wouldn't die. I mean the animation for the planet smashing even shows huge city size chunks flying into space. It would be really weird if your rinky dink T1 Radar Sat survived the collision.

Sorry for my postmaking deficiencies that was supposed to be related to

After the solid rock loses touch contact with the explosion it is no longer accelrating, it's free-falling. Orbits are round ie they take you back to the point from where you started. Therefore if the only acceleration happens at ground level it will return there. In order for to enter a stable orbit that doesn't intercept groun additional accelration would be need. Maybe some of that will be provided by the rocks crashing into each other but the vast majority of the mass is going to aero- or lithobreak on its first orbit. Neighboring pieces of rock will not have that big a relative velocity, they are both going outward from the impact point. When two bodies smash into each other they will continue to orbit in which ever planets orbit the collision happens but they are not going to enter any low eccentrity orbit about their barycenter. They will be retained "too close" to form a shell around the original surface.

I do agree that they would only accelerate from the initial collision, but the sheer force that would send that debris flying to their air would in some cases exceed escape velocity from orbit and just fly out into space (probably getting nudged by solor winds and sent to the Oort Cloud, would be flung into the stable orbit, or yes would be thrown into a relatively close orbit and fall back to earth.

But in the time the explosion happens, the debris flies into the atmosphere, hit each other and breaks into smaller pieces, those pieces hit more debris and satellites and break into pieces, then destroy everything in orbit and fall back to earth. And at that point most material would be pretty small. Dust or pebble size even.

And we are talking about and entire planet striking an entire planet. These aren't meteors or 1km asteroids. These are HUGE planetary bodies smashing into one another. Its an unimaginable amount of force.

A hypothesis for the formation of the moon is that a planet about the size as Mars hit Earth, and the moon formed out of the resulting debris field.


Edited for appalling grammar and word order.

It either escapes or fails to escape neither of which forms a long term hazard on the orbit. The rocks hit once as they ascend and once as they descend (that is if they are captured and don't escape).

Most of that enegry is going to be heat around the impact site but it's true that even the residuals are nothing to sniff at. You have to also take into account that the more energetic the mass the higher altitude it takes. Those that potentailly meet with the satellites horizontally have depleted their vertical velocity. Also when the explosion grows bigger it wants to move bigger chunks making less energy in proportion channel into orbit dangerous projectiles. Impacting with dust might be way more gracefull. You only take momentum proportional to your area instead of the whole chunk that is connected. And dust is more likely to impact over a longer period avoiding all the g-spikes, a difference between punching and pushing.
