Learn About Meteorites: Rollover Lips
When falling through our atmosphere on the way to an impact with the Earth, most meteorites spin and tumble, often acquiring the interesting sculptural shapes. A very few maintain a fixed orientation towards our planet's surface. Heat ablation may cause those meteorites to acquire a conical, dome, or shield-shape, reminiscent of the heat shield on the Mercury, Gemini and Apollo space mission capsules and such meteorites are described as being oriented.
