Springtime in the Solar System . In our case, we can use the tilt theory of the seasons to make a prediction: that any tilted planet will have seasons, and that the strength of these seasons will depend on the amount of the tilt. ... At summer solstice, the north pole points straight at the Sun; the north polar regions have tropical weather, but the Southern Hemisphere is in total darkness. ... With a little trigonometry, you can calculate the angle of the Sun and the intensity of solar heating. ...

. This image, made from data obtained by NASA's Dawn spacecraft, shows the mineral distribution in the southern hemisphere of the giant asteroid Vesta. The areas in purple have a higher proportion of diogenite minerals, and yellow areas have a higher proportion of eucrite minerals. Diogenites are silicate rocks with more magnesium than the eucrites, which are richer in iron. The mineral data lies on a mosaic obtained by Dawn's framing camera.
