Our solar system now
Our Solar System
now designated a dwarf planet (but retains its asteroid label), along with Pluto, which was discovered in 1930; Eris, found in 2003; Haumea, found in 2004; and Makemake, found in 2005. Our solar system formed about 4.6 billion years ago. The four planets closest to the Sun — Mercury, Venus, Earth, and Mars —
Planet Facts & Information
This is a table showing some facts on all the planets of our Solar System - and also the Moon. We are using the official list of 8 planets and 5 dwarf planets as defined by the International Astronomical Union (IAU).
NASA''s Eyes
Eyes on the Solar System. This simulated view of the solar system allows you to explore the planets, their moons, asteroids, comets and the spacecraft exploring them. You can also fast-forward or rewind time, and explore the solar system
Solar System Live
Welcome to Solar System Live, the interactive Orrery of the Web. You can view the entire Solar System, or just the inner planets (through the orbit of Mars). Controls allow you to set time and date, viewpoint, observing location, orbital elements to track an asteroid or comet, and a variety of other parameters.
Our solar system
The first section introduces our solar system and the objects within it and the second section looks at size and scale in our solar system. So let''s get started with the first section, our solar system. So we know that Earth is a planet that orbits the sun. There''s a little diagram of that on the screen now, of course that''s not to scale.
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
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.
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.
Dwarf Planets of our Solar System
Three years after NASA''s New Horizons spacecraft gave humankind our first close-up views of Pluto and its largest moon, Charon, scientists are still revealing the wonders of these incredible worlds in the outer solar system.

Pluto
Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006. NASA''s New Horizons was the first spacecraft to explore Pluto up close, flying by in 2015. Pluto was discovered in 1930 by astronomer Clyde
Solar System: Exploration
Humans have studied our solar system for thousands of years, but it was only in the last few centuries that scientists started to really figure out how things work. Earth as our eyes and ears and senses— only started in the 1950s. A scientific fleet of robots is out there right now exploring destinations from our Sun to interstellar space
How Many Planets Are There In The Solar System?
The solar system planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. This has been correct since 2006 when the International Astronomy Union actually defined what a "Planet" is and also what a "Dwarf Planet" is.
Planets of our Solar System
Planets of the Solar System. This page provides a brief description of each of the planets (and links to dwarf planets) of our solar system. You can also find out about the difference between planets, dwarf planets and small solar system bodies (SSSBs) here. Available as a poster here.
In Depth | Our Solar System – NASA Solar System Exploration
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as
The Planets Today : A live, central earth (geocentric) view of the
A Geocentric View of the solar system. This page provides a different way of looking at the solar system. It is geocentric and shows where the Sun and all the planets (and the moon) are in the sky.
Solar System Exploration
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, Haumea, Makemake, and Eris. Get the Facts.
The Sun
The Sun is the star at the heart of our solar system. Its gravity holds the solar system together, keeping everything — from the biggest planets to the smallest bits of debris — in its orbit. 18. Active Missions. 13. Upcoming Missions. Overview.
Our Solar System
Imagine entering our solar system from interstellar space. As you travel toward our Sun, you would move through three distinct regions. First you would pass countless icy worlds. Then you would enter the realm of the giant planets. Finally, you would reach the rocky planets closest to the Sun. Let''s take a look at our solar system—from the
Names of all the Planets and Moons of Our Solar System
This page shows the names of all the planets and also the names of the currently known moons. It also lists the names and locations of each Planet and Satellite discoverer (if known) and provides the meaning/derivation for each name. The planets are in order of the date of discovery.
