What objects make up our solar system

What is a Planet? | Planets – NASA Solar System Exploration

Here is the text of the IAU''s Resolution B5: Definition of a Planet in the Solar System: Contemporary observations are changing our understanding of planetary systems, and it is important that our nomenclature for objects reflect our current understanding. This applies, in particular, to the designation "planets".

Astronomy: The Solar System

The center of the Solar System is the Sun. The Solar System is made up of the Sun and all the planets, asteroids, and other objects that orbit the Sun. The Planets There are eight planets in our Solar System. Starting with the closest to the sun they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

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

About the Planets

Our solar system has eight planets, and five dwarf planets - all located in an outer spiral arm of the Milky Way galaxy called the Orion Arm. It is oval-shaped, and is one of the fastest rotating large objects in our solar system. Explore Haumea. Makemake Facts. Makemake is slightly smaller than Pluto, and is the second-brightest object in

1.2: Our Solar System

The Sun is the largest (in diameter) and most massive object in our Solar System. With a mass of 1.99 × 10 30 kg (which is about 330,000 times more massive than Earth), the Sun contains 99.8% of the total mass of the Solar System. There is a strong gravitational force between the Sun and the other objects in the Solar System, and all other

Our Sun: Facts

The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). It goes through phases of high and low activity, which make up the solar cycle. Approximately every 11 years, the Sun''s geographic poles change their magnetic polarity – that is, the north and south magnetic poles swap

Solar System

A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That''s because our sun is known by its Latin name, Sol. The solar system includes everything that is gravitationally drawn into the sun''s orbit. Use these resources to learn about

This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.These lists can be sorted according to an object''s radius and mass and, for the most massive objects, volume, density, and surface

10 Things to Know About the Kuiper Belt

The Kuiper Belt is one of the largest structures in our solar system — others being the Oort Cloud, the heliosphere and the magnetosphere of Jupiter. Its overall shape is like a puffed-up disk, or donut. Its inner edge begins at the orbit of Neptune, at about 30 AU from the Sun. (1 AU, or astronomical unit, is the distance from Earth to the Sun.)

Planet

Together, the sun, the planets, and smaller objects such as moons make up our solar system. Discovered in 1930, it was long considered the ninth planet in our solar system. But in 2006, the International Astronomical Union revised its definition of a planet. Under the new definition, a planet must be massive enough that gravitational forces

Haumea

Haumea Facts Haumea is an oval-shaped dwarf planet that is one of the fastest rotating large objects in our solar system. The fast spin distorts Haumea''s shape, making this dwarf planet look like a football. Discovery Two teams claim credit for discovering Haumea citing evidence from observations made in 2003 and 2004. The International Astronomical []

Small Bodies of the Solar System

The small bodies in the solar system include comets, asteroids, the objects in the Kuiper Belt and the Oort cloud, small planetary satellites, Triton, Pluto, Charon, and interplanetary dust. As some of these objects are believed to be minimally altered from their state in the young solar nebula from which the planets formed, they may []

Solar System

While astronomers have discovered thousands of other worlds orbiting distant stars, our best knowledge about planets, moons, and life comes from one place. The Solar System provides the only known example of a habitable planet, the only star we can observe close-up, and the only worlds we can visit with space probes. Solar System research is essential for understanding

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

Visualized: The Mass of the Entire Solar System

Perhaps not surprisingly, the Sun eclipses all other nearby objects by mass. At the heart of our solar system, this yellow dwarf''s gravity is what holds it all together. The Sun actually makes up 99.8% of our entire solar system''s mass —
