We are technically inside the Sun’s atmosphere
You might think it is ridiculous to say that the Earth is inside the Sun’s atmosphere since it is so far away. The truth is that the Earth is not actually inside it since atmospheres only include layers of gases emitted by a star or planet. However, the Earth is located within the star’s heliosphere.
The heliosphere is a round, magnetic field filled with protons and electrons from solar winds and contains all the system’s planets. It was believed to be bubble-shaped, but the Cassini spacecraft allowed us to observe that it was actually spherical.
