This diagram
represents Makemake's orbit in blue. The white ellipse in the middle is Neptune's orbit which, like the other planets, is in the
plane of the ecliptic. You can see how steeply tilted Makemake's orbit is to the ecliptic.
Orbits of two other dwarf planets are there too, Haumea in green and Pluto in red. When the dwarf planet's orbit is above the ecliptic the color is lighter than when it's below the ecliptic. The "Q" shows the aphelion (when the dwarf planet is farthest away from the Sun) and the "q" shows the perihelion (when the dwarf planet is closest to the Sun).
