Overview of our solar system

An Overview of the Solar System

Basics The solar system consists of the Sun; the nine planets, over 100 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are also many more planetary satellites that have been discovered but not yet been officially named.) The inner solar system contains the Sun, Mercury, Venus, Earth and Mars:

7.1 Overview of Our Planetary System – Astronomy

Key Concepts and Summary. Our solar system currently consists of the Sun, eight planets, five dwarf planets, nearly 200 known moons, and a host of smaller objects. The planets can be divided into two groups: the inner terrestrial planets and the outer giant planets. Pluto, Eris, Haumea, and Makemake do not fit into either category; as icy dwarf

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

Science 101: The Solar System

Transcript (English) - [Narrator] Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

17.3: 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

Solar System

On first glance, our solar system seems to be well understood. It includes a single star, planets, their moons, dwarf planets like Pluto and Ceres, and smaller bodies like asteroids, comets, and the outer solar system Kuiper Belt objects. Yet, scientists continue to discover fascinating new findings about our solar system, and Hubble has

This article details what the solar system is, the structure of the solar system, and relevant information regarding orbits, planets, moons, asteroids, and comets. The solar system consists of the Sun, its eight main planets, dwarf planets, tiny bodies

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. Saturn is a massive ball made mostly of hydrogen and helium. The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times.

solar system

The solar system is also known as a planetary system. Since the 1990s scientists have found many planetary systems beyond our solar system. In these systems, one or more planets orbit a star—just as the eight planets in our solar system orbit the Sun. These planets are called extrasolar planets.

Planetary Systems

Planetary Systems Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock. Similarly, exoplanetary systems are groups of non-stellar objects circling stars other than the Sun, and []

However, we shouldn''t forget about an often overlooked, yet significant part of our solar system. Those are the comets and asteroids, remnants from the formation of our system almost 4.6 billion years ago. Being part of a solar system tour, you wouldn''t just be observing the cosmos. Instead, you''d immerse yourself in a cosmic ocean, each
