Sample text

Is this not contradictory? In fact, there are some exceptions, called the Lagrange points, to the rule of clearing the neighborhood. In 1772, the Italian-French mathematician Joseph-Louis Lagrange (1736–1813) studied a restricted three-body problem. These problems consider three bodies and their respective gravitational interactions. In general, they are difficult to solve. In the restricted case, the mass of one body is negligible because it is too small compared to the others. Hence, we only have to consider the masses of two objects M1 and M2.

Hence, names of Greek heroes are to be chosen. Bodies at L5 are named after Trojan heroes as this group is considered to be the Trojan camp. Yet, there are two exceptions to this naming convention. (617) Patroclus, a Greek hero, is located at L5 and thus in the Trojan camp. On the other side, (624) Hektor, the famous Trojan hero that had been defeated by Achilles, belongs to the Greek camp at L4. How did that come about? The explanation is quite simple. They were named before the nomenclature was introduced.

8 Trojan Asteroids 49 Fig. 15 The diagram shows the position of the annual cycle of 2010 TK7 in selected future years, changing from its current position just ahead of the Earth to its farthest position from our planet in the year 2209. After that, the cycle reverses its drift and slowly moves back towards the Earth. It gets back to its current 2011 position around the year 2400, completing a full period of what is called “libration” (credit: NASA, Paul Chodas & Don Yeomans, NASA/JPL Near-Earth Object Program Office) Not much is known about them, as they are difficult to observe.
