Planet Sizes and Locations in Our Solar System

Mars, the red planet, is the seventh largest planet in our solar system. Mars is about half the width of Earth, and has an equatorial diameter of about 4,221 miles (6,792 kilometers). Mars is the fourth planet from the Sun, orbiting at an average distance of 141.6 million miles (227.9 million kilometers). Mars is about 49 million miles (79

Mercury Facts

Introduction Mercury''s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C). Despite its proximity to the Sun, Mercury is not the hottest []

Mars Facts

The Red Planet is actually many colors. At the surface, we see colors such as brown, gold, and tan. The reason Mars looks reddish is due to oxidization – or rusting – of iron in the rocks, regolith (Martian "soil"), and dust of Mars. This dust gets kicked up into the atmosphere and from a distance makes the planet appear mostly red.

Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter''s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. The composition of Jupiter is similar to that

Composition of the Solar System

Composition of the Solar System. Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the several hundred thousand asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.

Terrestrial planet compositions controlled by accretion disk

Compositional models for the terrestrial planets are constructed from the following data sets: composition of the Sun (i.e., > 99% mass of the solar system) (Lodders 2020), chemical trends for samples from a planet, satellite observations, and compositions of chondritic meteorites (i.e., the solar system''s building blocks of undifferentiated rock and metal mixtures) (Wasson

Earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life.This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water.Almost all of Earth''s water is contained in its global ocean, covering 70.8% of Earth''s crust.The remaining 29.2% of Earth''s crust is land, most of which is located in the form of

Saturn Facts

Introduction Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn''s. Saturn also has dozens of moons. From the jets of water that spray from Saturn''s moon Enceladus to the []

Exploring Venus: Planet Composition, Mythology, And Astrology

Planet Composition. Venus, often referred to as Earth''s sister planet due to their similar size and proximity to the Sun, has a composition that sets it apart in the solar system. Comprised mainly of a rocky mantle and a metallic core, Venus lacks the presence of water on its surface, resulting in a dry and desolate landscape.

6 FAQs about [Planet composition]

What are terrestrial planets made of?

Throughout the outer solar system, we find abundant water (mostly in the form of ice) and reducing chemistry. The terrestrial planets are quite different from the giants. In addition to being much smaller, they are composed primarily of rocks and metals. These, in turn, are made of elements that are less common in the universe as a whole.

What is the composition of Jupiter?

Despite its large size, its composition is rather simple. Jupiter is primarily composed of just two elements: hydrogen and helium, along with trace amounts of other chemicals such as water, sulfur, methane, and ammonia. Around 90% of Jupiter is hydrogen, while the remaining 10% is almost entirely helium.

What are the three main types of planets?

When you look at what planets are made of, you get three main groups: terrestrial planets, gas giants, and ice giants. Our Solar System’s terrestrial planets are Mercury, Venus, Earth, and Mars. The word “terrestrial” comes from the Latin “terra,” which means Earth. Terrestrial planets are primarily made of rocky material and have solid surfaces.

What are the 3 terrestrial planets in the Solar System?

Our Solar System’s terrestrial planets are Mercury, Venus, Earth, and Mars. The word “terrestrial” comes from the Latin “terra,” which means Earth. Terrestrial planets are primarily made of rocky material and have solid surfaces. Their main layers are the core, mantle, crust, and atmosphere.

Which planets have a thick atmosphere?

Mars’ atmosphere is very thin, made mostly of carbon dioxide. Earth’s is rich in nitrogen and oxygen, helping life thrive. Venus’ thick carbon dioxide atmosphere is responsible for the planet’s greenhouse effect and searing temperatures. Jupiter and Saturn are the Solar System’s gas giants.

Are all planets dominated by different elements?

Certainly their compositions are dominated by different elements. Let us look at each type in more detail. The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium.
