You can try to use a highlight layer for the atmosphere and a glow layer to make the emissive texture more visible:
Thank you very much，I see refraction in the atmosphere，How to add refraction effect without affecting the original material ? And this reflection blur？
I have no idea for the refraction. For the other one, may bloom would do it.
Did you check my very old demo here:
Babylon.js - Planet demo (babylonjs.com)
You need to lower the glow layer intensity.
