Professor John Chiang of UC Berkeley explains the impact of Earth's axial tilt and orbital eccentricity on global climate. He ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) and by analyzing archival Arecibo Observatory data, ...

Some worlds, however, have more elongated orbits. The degree of elongation, known as eccentricity, is measured on a scale of ...

Trans-Neptunian objects (TNOs) are icy bodies that vary widely in size, from large dwarf planets like Pluto and Eris—each ...

Keep your eye on the ball” is a motto for many athletes—and for astronomers trying to find Earth-threatening space rocks ...

and orbital eccentricity. Candidate stars were also cross-referenced with the dataset from Gaia, which is designed to capture data about stars. Utilizing all the tools, the authors identified ...

The degree of elongation, known as eccentricity, is measured on a scale of 0 (for a perfect circle) to 1 (a hyperbola). Earth's orbital eccentricity is 0.017; Mars' is 0.055, and Mercury's is 0.206.

Further, as the velocity of impact must have been comparable with an orbital velocity on account of the high eccentricity of the orbits, the colliding planetesimals must in nearly all cases have ...
