In corn, purple kernels (P) are dominant to yellow kernels (p). You have a plant with an unknown genotype that has a phenotype of purple kernels. You perform a testcross and find that all of the offspring are purple.
The layout of the solar system, including the Oort Cloud, on a logarithmic scale. Credit: NASA. In the furthest reaches of the Solar System is the Oort Cloud; a theorized cloud of icy objects that could orbit the Sun to a distance of 100,000 astronomical units, or 1.87 light-years away.
Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies such as comets and asteroids. Of those that orbit the Sun indirectly, two are larger than the smallest planet. The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter.
