The Synthesis of "elliptical orbits"

Discover orbital eccentricity, the key measure defining the shape of a planet's path from a perfect circle to an extreme ellipse. Learn why it matters.

Discover Johannes Kepler, the 17th-century astronomer whose laws of planetary motion revolutionized our understanding of the solar system.

Discover Johannes Kepler, the 17th-century astronomer who revolutionized our understanding of the cosmos with his laws of planetary motion.

Discover elliptical galaxies, the smooth, oval-shaped star cities that hold clues to the universe's history and evolution. Learn why they matter.

Discover orbital mechanics, the science of how objects move through space. Learn how gravity and momentum dictate the paths of planets and spacecraft.

Discover Kepler's three laws of planetary motion, which describe how planets orbit the Sun. Learn why these fundamental principles of astronomy matter.

Discover Sedna, one of the most distant objects in our solar system. Learn why this mysterious dwarf planet's orbit hints at a hidden giant planet.

Discover Eris, the distant dwarf planet whose discovery challenged our definition of a planet and led to Pluto's reclassification.

Discover Low Earth Orbit (LEO), the orbital highway for satellites, the ISS, and services like Starlink. Learn why this space region is buzzing.

Discover geosynchronous orbit (GSO), the high Earth orbit that allows satellites to match Earth's rotation, enabling modern communication.
