Researchers at the University of Hawaii, Honolulu say they have found that Earth could have at least two moons orbiting it at any one time, after finding a near-earth satellite (NES) in our orbit just a few years ago. The scientists then created a model showing how other satellites interact with our gravitational pull. "At any given time, there should be at least one natural Earth satellite of 1-meter diameter orbiting the Earth,” said Mikael Granvik of UH Honolulu and his...

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
