Solar system - Formation of the outer planets and their moons

WebThe planets are of two different types. The four inner planets, those closest to the Sun, are Mercury, Venus, Earth, and Mars. They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases. What are planets? Where did they come from? WebThe small particles drifting in orbit around the developing Sun were initially no bigger than grains of sand. But over time, the particles clustered together, building up into larger and larger bodies, known as planetesimals. While these objects were still relatively small, the growth process was fairly slow and steady.

WebMar 16, 2011 · Planetesimals are small objects that can range from millimeters (mm) to the size of several hundred kilometers (km), formed out of grains of dust that collide and get stuck together to form larger bodies such as planets. The planetesimal theory was first proposed by a Soviet astronomer by the name of Viktor Safronov. It has been inferred that about 3.8 billion years ago, after a period known as the Late Heavy Bombardment, most of the planetesimals within the Solar System had either been ejected from the Solar System entirely, into distant eccentric orbits such as the Oort cloud, or had collided with larger objects due to the regular gravitational nudges from the giant planets (particularly Jupiter and Neptune). A few planetesimals may have been captured as moons, such as Phobos and Deimos (t…
