· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

Discovery and exploration of the Solar System

The Solar System is one of many planetary systems in the galaxy. [1] [2] The planetary system that contains Earth is named the "Solar" System. The word "solar" is derived from the Latin word for Sun, Sol (genitive Solis). Anything related to the Sun is called "solar": for example, stellar wind from the Sun is called solar wind.

Solar System History 101

Our solar system is a wondrous place. Countless worlds lie spread across billions of kilometers of space, each dragged around the galaxy by our Sun like an elaborate clockwork.. The smaller, inner planets are rocky, and at least one has life on it. The giant outer planets are shrouded in gas and ice; miniature solar systems in their own right that boast intricate rings

In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Top Reasons to ♥ Solar Energy

Solar is an economic engine—about 250,000 people work in the U.S. solar industry these days and there are more than 10,000 solar businesses around the country. Solar costs have fallen dramatically. The cost of an average-size residential solar energy system decreased 55% between 2010 and 2018, from $40,000 to $18,000—and that''s before

Jupiter''s Influence

According to most theories, Jupiter has a dense core of heavy elements that formed during the early solar system. The solid core of ice, rock, and metal grew from a nearby collection of debris, icy material, and other small objects such as the many comets and asteroids that were zipping around four billion years ago.

Solar System Facts

The solar system was formed approximately 4.6 billion years ago by the collapse of a giant molecular cloud.The mass at its centre collected to form the Sun and a flat disk of dust around it.
