Research has shown that the Earth trails an asteroid barely a kilometer across in its orbit about the Sun – only the second such body to have ever been spotted. It goes around the Sun on average two ...
Physicists have discovered a tiny asteroid, about one kilometer wide, that is locked into the same orbit as Earth—only the second such cosmic body of its type that has been identified to date. And now ...
Control of chaos in the vicinity of the Earth–Moon L5 Lagrangian point to keep a spacecraft in orbit
The concept of Space Manifold Dynamics is a new method of space research. We have applied it along with the basic idea of the method of Ott, Grebogi and York (OGY method) to stabilize the motion of a ...
Two micro-satellites originally launched into Earth’s orbit in 2007 by NASA have been redirected by University of California, Berkeley, scientists toward new orbits around the Moon, extending study of ...
(WHTM) — It’s so simple to understand. Objects orbiting the Earth are not going fast enough to escape Earth’s gravity, but are going fast enough that they don’t fall back down. They ceaselessly fall ...
