English: This diagram shows impact of the opposition effect on the discovery of Near-Earth objects. Over half (53%) of the discoveries were made in 3.8% of the sky, in a 22.5° cone facing directly away from the Sun, and the vast majority (87%) were made in 15% of the sky, in a 45° cone facing away from the Sun. Only 13% of the discoveries fell outside of these regions.
Sizes and distances are to scale. Units: LD. The cone angle is the angle between the cone surface and cone axis. Projection of data onto a 2D surface preserves distances between asteroid position and both Sun and Earth. It also preserves the solar elongation (angle between Sun, Earth and asteroid) and phase (angle between Sun, asteroid and Earth). Relative distances and angles between asteroids are not preserved by the projection. Discoveries inside the 22.5° cone indicated in lime green. Discoveries inside the 45° cone indicated in yellow. Discoveries outside the 45° cone indicated in orange, notably including 99942 Apophis, which is marked. This diagram is intended for the following articles: |
