"Dead Zone" Asteroid Found Following Neptune

Neptune's got company—a supposed Trojan asteroid caught in a gravitational "dead zone" made by a cosmic tug-of-war between the gravitational areas of the gas giant planet and the sun. In that dead zone the sun and Neptune's gravitational attracts are or so equal. As a consequence, the asteroid is held at a given distance behind the planet, accompanying—but not revolving—Neptune as it circulates the sun.
These areas where the gravity of the sun and a planet balance out are spoke Lagrangian points. Lagrangian points L4 and L5—where the new Neptune asteroid was found—are the most static. The little, rocky bodies viewed in these zones deal their host planet's orbits.
Trojans have been found at the L4 and L5 points of Jupiter, Mars , and even of two of Saturn moons. The Trojans have an bent orbit, which means they must have joined line in the solar system's early days, before Neptune's orbit had changed.
Until now, scientists had discovered six Neptune Trojans, in the L4 zone, which orbits before of Neptune. Trojans in the dragging, L5 zone eluded investigators because the Milky Way's bright light gets in hard to pick out the space rocks.
