Here's why this is significant:

* Ecliptic: The ecliptic is the plane of Earth's orbit around the Sun.

* Uranus's Tilt: Uranus is tilted on its side at about 98 degrees. This means its axis of rotation is almost parallel to the plane of its orbit, unlike most other planets in our solar system.

This extreme tilt causes Uranus to experience very long periods of darkness and sunlight in different parts of its year.
