[suggestion] strange object spottable in the sky

Hello dear engineers, here's my suggestion

This is a planet that doesn't have name because it's an unknown planet, you could register this planet as "Unknown_Space_Object-01"

This would be a dark planet, with an opaque atmosphere. This planet is really hard to spot in the sky (almost invisible to see from planets with atmosphere), so it's difficult to go.

When you enter the atmosphere of this planet, that would be a really dark place and flat area to land with a big ship would be really rare, so a shuttle would be the best option to land. Spotlights would be required if you want to see something, else this would be only an opaque and permanent black fog.

On this planet, the gravity is really huge (maybe something like 3.00g) and there would be an extreme wind (~50m/s).

If you succeed to land, you would find a really unwelcoming place. you'll find holes everywhere and large dark rock peaks. Also, flying with your jetpack will not be a good option since the wind and the gravity would make your flight the last, so the best way to travel would be with a well prepared rover. On this planet there would be no NPC stations since it's a unknown planet.

The temperature would be cold (not freeze like in space) and there wouldn't be O2, but a toxic gaz that you shouldn't try to breath. The ground is mainly composed of iron, stone and platinium (the reward for the daring engineers). But don't think that the endless dark weather and the extreme gravity is your only enemy, because you'll find there strange slimy monsters, we call them the Dllogss.

Only the most reckless engineers have seen Dllogss, but we never saw them again, that's why you'll find a lot of shipwreck on the surface. Dllogss have no eyes but they can hear you, and your thrusters, or hydrogen engines too, so be careful and keep your rocket launcher PRO-1 in your backpack.

If you succeed to escape this planet, congratulations ! you escaped from hell.
