Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth''s water is contained in its global ocean, covering 70.8% of Earth''s crust. The remaining 29.2% of Earth''s crust is land, most of which is located in the form of continental

The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C). The heliosphere extends beyond the orbit of the planets in our solar system. Thus, Earth exists inside the Sun''s atmosphere. Outside

3.1: Origin of Earth and the Solar System
The young sun also blasted the solar system with raging solar winds (winds made up of energetic particles), which helped to drive lighter molecules toward the outer part of the protoplanetary disk. The objects in our solar system formed by accretion. Early in this process, mineral and rock particles collected in fluffy clumps because of static
Facts About Earth
When Earth was a young planet, a large chunk of rock smashed into it, displacing a portion of Earth''s interior. The resulting chunks clumped together and formed our Moon. With a radius of 1,080 miles (1,738 kilometers), the Moon is the fifth largest moon in our solar system (after Ganymede, Titan, Callisto, and Io).
Planet Sizes and Locations in Our Solar System
Venus is the sixth largest planet in the solar system. Venus is about the same width as Earth, and has an equatorial diameter of about 7,521 miles (12,104 kilometers). For this reason, Venus is sometimes known as Earth''s twin. Venus is the second planet from the Sun, orbiting at an average distance of 67.2 million miles (108 million
18.1: Introduction to the Solar System
Today, we know that our solar system is just one tiny part of the universe as a whole. Neither Earth nor the Sun are at the center of the universe. However, the heliocentric model accurately describes the solar system. In our modern view of the solar system, the Sun is at the center, with the planets moving in elliptical orbits around the Sun.
Chapter 1: The Solar System
The solar system consists of an average star we call the Sun, its "bubble" the heliosphere, which is made of the particles and magnetic field emanating from the Sun - the interplanetary medium - and objects that orbit the Sun: from as close as the planet Mercury all the way out to comets almost a light-year away.A light year is the distance light travels in a year, moving at about

What Is the Solar System?
Solar System Formation. The solar system is located in one of the spiral arms of the Milky Way galaxy. It was born about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed. Most of the material was pulled toward a central point: nearly all of the solar system''s mass—99.8%—is in the Sun.
7.1 Overview of Our Planetary System
In our imaginations, let us build a scale model of the solar system, adopting a scale factor of 1 billion (10 9)—that is, reducing the actual solar system by dividing every dimension by a factor of 10 9. Earth, then, has a diameter of 1.3 centimeters, about the size of a grape.

The most cratered planet of the solar system is Mercury. Some believe that Saturn and Jupiter came close once and thus provoked the Great Flood on Earth. Every 15 years, the rings of Saturn briefly disappear from view due to their angle. Saturn produces the eeriest radio emissions in the solar system.
