| A partial solar eclipse is when the Moon only covers part of the solar disc.[image] |
|
|
Term
|
Definition
| when the Moon appears to cover the entire solar disc. Total solar eclipses are only visible from a very small area on Earth, a narrow track that moves across the Earth's surface (as the Earth rotates). The partial phase of a total eclipse lasts about an hour. In any one place, totality (when the solar disc is entirely covered) lasts no more than 8 minutes. During totality, the sky is dark enough to see stars in the sky. |
