Moons of Our Solar System
How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon. Since it was named before we learned about other planetary satellites, it is called simply "Moon." According to the NASA/JPL Solar System Dynamics team, the current tally []

Our Solar System
Worlds in our outer solar system consist mostly of water ice, other ices, and some rock. Various processes have shaped their surfaces into strange landscapes. Because they are so far from Earth, we are just starting to learn about them, how they formed, and how they interact with the rest of our solar system.

Both apps show a solar system map - a "plan view" of the planets laid out in the plane of the ecliptic (the flat plane in which all the main planets move about the Sun). As you may know, the Earth''s axis is tilted over by 23.4 degrees and the Earth''s North Pole currently points at the star known as Polaris - the North Star. The app is
Understanding Earth as a System
Viewing Earth as a system means understanding each of the system''s parts and how they work together. We can learn about the Earth system by beginning with observation. Scientists explore extreme weather events in the context of changing climate, earthquakes and volcanic eruptions in the context of tectonic shifts, and losses in biodiversity
How Many Planets are in our Solar System? | Facts & Amount
A star that hosts planets orbiting around it is called a planetary system, or a stellar system, if more than two stars are present. Our planetary system is called the Solar System, referencing the name of our Sun, and it hosts eight planets.. The eight planets in our Solar System, in order from the Sun, are the four terrestrial planets Mercury, Venus, Earth, and Mars, followed by the two gas
Earth, our home planet | The Planetary Society
Earth is the fifth-largest planet in our Solar System and the third planet from the Sun. It sits in our Sun''s habitable zone, the not-too-hot, not-too-cold region around a star where liquid water can exist on a planet''s surface. Our planet''s churning liquid-metal core generates a magnetic field that shields us from most of the Sun''s
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.

Why is our planetary system called the Solar System?
Our planetary system is called “the solar system” because we use the word “solar” to describe things related to our star, after the Latin word for Sun, "solis." So far, we've only know about life on Earth, but NASA is searching for life on other worlds in our solar system and beyond.
Is Earth a planet or a heliocentric system?
Since the Copernican revolution of the 16th century, at which time the Polish astronomer Nicolaus Copernicus proposed a Sun-centred model of the universe (see heliocentric system), enlightened thinkers have regarded Earth as a planet like the others of the solar system.
