The Gerard P. Kuiper Prize is awarded annually by the Division for Planetary Sciences of the American Astronomical Society for outstanding lifetime achievement in the field of planetary science. The prize is named for Gerard P. Kuiper .
The most widely accepted model of planetary formation is known as the nebular hypothesis. This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud. The gas that formed ...
1951 – Gerard Kuiper argues for an annular reservoir of comets between 40 and 100 astronomical units from the Sun having formed early in the Solar System's evolution, but he did not think that such a belt still existed today. [176] Decades later, this region was named after him, the Kuiper belt.

The Kuiper belt was named after Dutch-American astronomer Gerard Kuiper, regarded by many as the father of modern planetary science, though his role in hypothesising it has been heavily contested. In 1951, he proposed the existence of what is now called the Kuiper Belt , a disk-shaped region of minor planets outside the orbit of Neptune , which ...
