How Can I Create a Snapchat Planets–Style Effect in CorelDRAW 2019?

I’m trying to create a Snapchat Planets–style graphic effect in CorelDRAW Graphics Suite 2019, but I’m not sure which tools or techniques will give me that smooth, glowing, planet-like look.
Could anyone guide me on how to recreate something similar using gradients, blends, transparency tools, or any other features in CorelDRAW 2019?
If there’s a simple step-by-step method or any helpful tips, I’d really appreciate it.
