Welcome back to Cosmos in a Pod! I’m your host, [Host Name], and today we’re diving into the fascinating story of how planets form around stars. From tiny grains of dust to sprawling worlds, let’s uncover the secrets of planetary formation.

Episode Highlights:

Protoplanetary Disks: The Birthplace of Planets

• Surrounding young stars, these swirling disks of gas and dust are where planets begin to form.
• Temperature variations in the disk determine the materials and types of planets that emerge.

Step 1: Dust to Pebbles

• Tiny grains of dust collide and stick together through electrostatic forces, forming pebbles.
• Ice-coated grains in outer regions clump more easily, leading to larger bodies.

Step 2: Pebbles to Planetesimals
