The Photosphere is the layer closest to the sun among the three layers that make up the sun's "atmosphere" (Photosphere, Chromosphere, and Corona).
The Sun's Atmosphere Layers
To understand which layer is closest, let's look at the structure of the Sun's atmosphere. The Sun's atmosphere is composed of three main layers:
- Photosphere: This is the innermost layer and the one we see most easily. It's considered the "surface" of the Sun.
- Chromosphere: Lies above the Photosphere.
- Corona: The outermost layer, extending far into space.
| Layer | Relative Position to the Sun | Visibility |
|---|---|---|
| Photosphere | Innermost | Easily visible |
| Chromosphere | Middle | Visible during eclipses |
| Corona | Outermost | Visible during eclipses |
Therefore, according to the provided information, the Photosphere is closest to the sun.
