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.
Diameter of the solar system at light speed: 1.182 x 1016 / 3 x 108 = 3.94 x 107 light-seconds = 456 light-days = 1.25 light-year. First of all, let's pick something to be the end of the solar system, so that we can agree. on what's in and what's out. For our first estimate, let's say everything that's double the distance to Pluto is in. Pluto's average distance from the sun is listed as 5.91 billion km. Double that is 11.82 billion km.
