In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. 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 Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Solar System

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

What Are the Chances That Earth Will Collide With Mars, Mercury, or Venus?

Will Earth meet its fiery doom when the orbits of the planets in our solar system become destabilized, leading Mars, Mercury, or Venus to crash into our home turf? A new study predicts that there is indeed a very slim possibility that such a cataclysm will rock our world, but notes that the possible collisions wouldn''t happen for more than 3

18.2: Inner Planets

From left to right, they are Mercury, Venus, Earth, and Mars. Unlike the outer planets, which have many of satellites, Mercury and Venus do not have moons, Earth has one, and Mars has two. Of course, the inner planets have shorter orbits around the Sun, and they all spin more slowly. Geologically, the inner planets are all made of cooled

5 The Inner Planets: The Key to Understanding Earth-Like Worlds

Earth''s inner solar system companions, Mercury, Venus, the Moon, and Mars, are diverse bodies, each of which provides data critical for understanding the formation and evolution of habitable worlds like our own. These terrestrial (or rocky) planetary bodies have a range of compositions and geologic histories—each is a unique world that

Size of Planets in Order

Earth''s "twin planet" Venus is only slightly smaller than Earth with a diameter of 12,104 km. Venus also has a similar gravitational pull of 8.87m/s 2 to that of Earth''s 9.81m/s 2 . 7. The red planet of Mars has a diameter of only 6,780 km. This makes it 20.5 times smaller in diameter than Jupiter.

Gravitational Pull of the Planets

Mars has a very low gravitational pull of only 3.71 m/s2. If you weigh 100 lbs on Earth you would only come in around 38 lbs on the red planet. 8. At 3.7 m/s2, Mercury''s gravitational pull almost exactly the same as that of Mars. Someone weighing

Solar System Exploration

The mean temperature is the average temperature over the surface of the rocky planets: Mercury, Venus, Earth, and Mars. Dwarf planet Pluto also has a solid surface. But since the gas giants don''t have a surface, the mean is the

Terrestrial Planet Facts (The Inner Planets)

The four innermost planets of our solar system (Mercury, Venus, Earth and Mars) are called the "terrestrial" planets. The name comes from the word "telluric" derived from the Latin words "terra" and "tellus", used to refer to Earth. They are made mostly of silicate rocks and metals, with solid surfaces and atmospheres that range

Distance Between Planets Of The Solar System | KM & Current

The Astronomical units (AU) column is the average distance between Earth and the Sun and is the most common way for scientists to measure distance in our Solar System. Below is a table of the distances between each of the planets in our solar system.

Planet Sizes and Locations in Our Solar System

Venus is the sixth largest planet in the solar system. Venus is about the same width as Earth, and has an equatorial diameter of about 7,521 miles (12,104 kilometers). For this reason, Venus is sometimes known as Earth''s twin. Venus is the second planet from the Sun, orbiting at an average distance of 67.2 million miles (108 million

Terrestrial

The Basics: What is a Terrestrial Planet? In our solar system, Earth, Mars, Mercury and Venus are terrestrial, or rocky, planets. For planets outside our solar system, those between half of Earth''s size to twice its radius are considered terrestrial and others may be even smaller.
