Orbita

The video tutorial explains the concept of orbits, describing how planets and moons revolve around larger celestial bodies due to gravity. It covers the elliptical shape of orbits, the role of gravity, and how time is measured based on planetary orbits. The tutorial also discusses objects orbiting Earth, including natural satellites like the moon and artificial satellites. It explains how Earth's orbit and tilt create seasons and concludes with a thought experiment on altering a planet's orbit to change the length of a year.
