I need help with creating a planet for a space exploration RP-like game I am working on

[computerwiz9 (Josh)]

Hi, I am working on a game where one of the main features of the game would be the ability to land in a planet’s atmosphere and being able to explore (albeit limited) on the surface of the planet.
However, how would I go about doing this?? The current build I have been experimenting with has been with meshes and decals, but is there any other way? Is it possible to have a localized sky-box within the planet that can convey an atmosphere of some sort? The current one I have right now does not look good at all and is made with a mesh. Below are pictures of the outside and inside of what I currently have. I feel like it looks really outdated right now.

Any feedback is appreciated thanks!!!

I have made something like this before but the sky only has a solid color and its transparency depends from where the player’s camera is

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")

local FakeAtmosphere = ReplicatedStorage:WaitForChild("FakeAtmosphere"):Clone()
local Planets = workspace.Planets
local Camera = workspace.CurrentCamera

local PlanetsWithAtmosphere = {}

FakeAtmosphere.Parent = workspace

function Distance(A: Vector3, B: Vector3)
	return (A - B).Magnitude
end

function NearestPlanet()
	local NearestPlanet, NearestDistance
	for _, Planet in pairs(PlanetsWithAtmosphere) do
		local Distance = Distance(Camera.CFrame.Position, Planet.Position)
		if Distance > 100000 or (NearestDistance and Distance >= NearestDistance) then
			continue
		end
		NearestDistance = Distance
		NearestPlanet = Planet
	end
	return NearestPlanet
end

local function GetValue(x: number , Min: number, Max: number): number
	local range = Max - Min
	return math.clamp(1 - (x - (Min)) / range, 0, 1)
end

for i, Planet in pairs(Planets:GetChildren()) do
	if Planet:IsA("BasePart") and Planet.Data.HasAtmosphere.Value == true then
		table.insert(PlanetsWithAtmosphere, Planet)
	end
end

RunService.RenderStepped:Connect(function()
	FakeAtmosphere.CFrame = Camera.CFrame
	
	local NearestPlanet = NearestPlanet()
	local PlanetModel = Planets.Model:FindFirstChild(NearestPlanet.Name .. "Model")
	local AtmosphericData = NearestPlanet:FindFirstChild("Data"):FindFirstChild("HasAtmosphere")
	
	FakeAtmosphere.BrickColor = AtmosphericData.Color.Value
	
	local Range = GetValue(Distance(Camera.CFrame.Position, NearestPlanet.Position), AtmosphericData.Start.Value, AtmosphericData.End.Value)
	
	FakeAtmosphere.Transparency = AtmosphericData.Density.Value / Range
	PlanetModel.Atmosphere.Transparency = Range * 2
	
	if Range > 0 then
		FakeAtmosphere.Transparency = 1
	end
end)

End meaning the distance from the center of the planet to where the atmosphere should end

and Start basically meaning where the atmosphere is at its fullest (from where the surface is from the center aka radius)
