It's called Earth. Like all planets it's roughly spherical in shape. Earth rotates on its axis and we call the time it takes to complete one rotation a.
All the planets orbit anti-clockwise as seen from "above" the Solar System (i.e. above Earth's North Pole). All planets orbit in roughly the same plane, forming an overall disc shape. Mercury and Venus orbit alone with no moons. Earth has.

At a relatively smaller scale, we know that galaxies are made up of stars and their constituents, our own Solar System being one of them.

Artist''s conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other
5 · solar system, assemblage consisting of the Sun —an average star in the Milky Way Galaxy —and those bodies orbiting around it: 8 (formerly 9) planets with more than 210 known
17.2 Overview of Our Planetary System [1]. The solar system consists of the Sun and many smaller objects: the planets, their moons and rings, and such "debris" as asteroids, comets, and dust cades of observation and spacecraft exploration have revealed that most of these objects formed together with the Sun about 4.5 billion years ago.
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.

Astronomers sometimes divide the Solar System structure into separate regions. The inner Solar System includes Mercury, Venus, Earth, Mars, and the bodies in the asteroid belt. The outer Solar System includes Jupiter, Saturn, Uranus, Neptune, and the bodies in the Kuiper belt. Since the discovery of the Kuiper belt, the outermost parts of the Solar System are considered a distinct
The inner Solar System includes Mercury, Venus, Earth, Mars, and the bodies in the asteroid belt. The outer Solar System includes Jupiter, Saturn, Uranus, Neptune, and the bodies in the Kuiper belt. [ 35 ]
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
Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The Universe . Exoplanets; The Search for Life in the Universe; Stars; Galaxies; Black Holes; The Big Bang; Dark Matter & Dark Energy; The Solar System . The Sun
Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms.
The solar system comprises the sun and everything else in its orbit, including comets, moons, planets, asteroids, and meteoroids. It begins with the sun, known as Sol to the ancient Romans, and extends past the four inner planets through the Asteroid Belt to the four gas giants, on to the disk-shaped Kuiper Belt, and far beyond to the teardrop-shaped heliopause.
In the billions of years since, stars, galaxies, and clusters of galaxies have formed and re-formed—eventually yielding our home galaxy, the Milky Way, and our cosmic home, the solar system
Our solar system is in one of the Milky Way galaxy''s spiral arms called the Orion Spur. 5. A Long Way Around Our solar system takes about 230 million years to orbit the galactic center. 6. Spiraling Through Space The Milky Way is a barred spiral galaxy. 7. Room to Breathe Our solar system has many worlds with many types of atmospheres. 8.
Learn about the planets in our solar system. The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto,
What does the Solar System Comprise? Ans: Our solar system is composed of the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, as well as dozens of moons and millions of asteroids, comets, and meteoroids that are all gravitationally linked to the Sun. Q.5. What is another theory for the origin of the universe?

4 · 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. Concurrent sea voyages provided practical proof that Earth is a globe, just as Galileo''s use of
Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across.

Many people are not clear about the difference between our Solar System, our Milky Way Galaxy, and the Universe. Let''s look at the basics. Our Solar System consists of our star, the Sun, and its orbiting planets (including Earth), along with numerous moons, asteroids, comet material, rocks, and dust.Our Sun is just one star among the hundreds of billions of
Our solar system began to form around 5 billion years ago, roughly 8.7 billion years after the Big Bang. A solar system consists of a collection of objects orbiting one or more central stars. All solar systems start out the same way. They begin in a cloud of gas and dust called a nebula. Nebulae are some of the most beautiful objects that have
