How do I make this CFrame movement less choppy?

I'm creating a tool for a game that has parts orbiting around the player. Currently, I'm listening for the RunService.Heartbeat event in a module that moves three parts around a player. On the server, the parts move smoothly, but on the client, the parts move in a choppy manner. I'm aware that this is because the server can only send updates to the client at 20Hz, but I don't know how to approach switching this movement over to RenderStepped while still having the same look to other players. What should I do?

On the client: https://gyazo.com/472ec68efb53c460f7c6e2d0417a325e

On the server: https://gyazo.com/472ec68efb53c460f7c6e2d0417a325e

Here is my code:

local Jutsu = {}
	Jutsu.spawn = function(Player, Name, Antiex)
	local i = 0
	local speed = 0.1
	local speed2 = .03
	local speed3 = .06
	local incline = math.rad(45)
	local incline2 = math.rad(-45)
	local incline3 = math.rad(0) 
	local distance = 5
	
	local Scorch = script.Scorch
	local ball = Scorch:Clone()
	ball.Parent = workspace
	local ball2 = Scorch:Clone()
	ball2.Parent = workspace
	local ball3 = Scorch:Clone()
	ball3.Parent = workspace
	local planet = Player.Character.Torso


	spawn(function()
		wait(30)
		movement:Disconnect()
		ball:Destroy()
		ball2:Destroy()
		ball3:Destroy()
	end)

	movement = game:GetService("RunService").Heartbeat:Connect(function()
			i = i + 1
			ball.CFrame = planet.CFrame * CFrame.fromEulerAnglesXYZ(incline, i * speed3, 0) * CFrame.new(0, 0, distance)
			ball2.CFrame = planet.CFrame * CFrame.fromEulerAnglesXYZ(incline2, i * -speed, 0) * CFrame.new(0, 0, distance)
			ball3.CFrame = planet.CFrame * CFrame.fromEulerAnglesXYZ(incline3, i * speed2, 0) * CFrame.new(0, 0, distance)
	end)
	
	end	
return Jutsu

Extra note: When I finish fixing the movement, I plan to add damage to all of the parts.

Instead use SetPrimaryPartCFrame:lerp(finishPos, acceleration) or use BodyPosition or BodyVelocity.
