The four known Neptune Trojans are shown in their position 60 degrees ahead of Neptune.



An asteroid has been newly spotted in Neptune’s orbit. This asteroid indicates the existence of a much larger cloud of rocks in that region, though it is not seen yet.



The asteroids in their main belt between Mars and Jupiter might be even les than the number of these found in the orbit of Neptune, according to the new research.



This newly found asteroid is one of four known Neptunian ‘Trojan’ asteroids. The Trojans orbit in lockstep with the planet. These asteroids orbit on its circular orbit around the Sun, in 60° — or about 5 billion kilometers — ahead of Neptune.



The orbit is a gravitationally stable location and is called a Lagrange point. But the newly-found asteroid is unique in its own way. Its orbit is tilted 25° relative to the plane of the solar system.
