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.
Our Sun is a fairly average star in the Main sequence: Stars range is size from white dwarfs with ca.a radius just .01 times that of our own sun, although their mass is about the same. Supergiants may have diameters several hundred times the size of our Sun. Sadly, we don't yet know the full scope of the sizes of other solar systems to compare to our own.
