Dawson in some cases studies debris disks, but she is also very interested in understanding the formation of planets that look nothing like those in our solar system. WebbThrough Brahe’s astronomical measurements and Kepler’s own drawings of the geometrical relationship between the Sun and Mars in various parts of the planet’s orbit, Kepler discovered that planets moved faster when they were closer to the Sun. From this realization, he concluded that the orbit of Mars was elliptical, not circular.
WebbThe Solar System is the system of objects that orbit the Sun directly or indirectly. Planets in the solar system are defined as celestial bodies that orbit the Sun, that are heavy enough for gravity to squeeze them into a spherical shape, and that have "cleared the neighborhood" around their orbit.
