Planets – Science Game
This science games helps in learning about different planets appearance and features. We live on a star called the Sun. What do planets look like? There are three kinds: rocky, gaseous and asteroidal. These bodies have extended atmospheres, thick crusts, and rocky cores. Each one is different, but all have one basic thing in common: they orbit the Sun. What makes these objects different? You'll learn about them in this article. Ultimately, you'll have a better understanding of the world around us.
Large celestial bodies orbiting the Sun
The process of studying large celestial bodies orbiting the Sun is constantly evolving. Technological development around the world is essential for product excellence. As such, astronomers are constantly searching for advanced methods to observe celestial bodies. The major satellites of Jupiter, Saturn and Uranus orbit in the same plane as the planets. The moons of these planets orbit at a slightly different rate. These satellites also share similar properties.
They have a thick crust
There are many theories regarding why planets have a thick crust, including the formation of oceans on the surface and the formation of volcanic rock. The crust of a planet is made up of several layers, the outermost being the lithosphere, which is dense and brittle. The lithosphere gradually turns into the softer asthenosphere. The lithosphere is thick on small planets, and thin on large planets. Thicker layers in the crust of Earth retain more heat. For example, the lithosphere of the Moon is two kilometers closer to Earth than its geometric center. This thin crust probably reflects the gravity of the Earth billions of years ago, and the outermost layer of the Moon's crust is several kilometers thick. Venus' lithosphere is slightly thicker than the lithosphere of Earth.
They have an extended atmosphere
The reason why planets have an extended atmosphere is the same reason Earth does: gas. Extrasolar planets also contain gas. Some have been observed to emit hydrogen into their extended atmospheres, while others have been detected to have minimal masses of 15 Earth masses. Outgassing is one of the most common sources of atmospheres for smaller terrestrial planets. In fact, planets with extended atmospheres are known to have more water than their terrestrial counterparts.
They have a rocky core
Gas giants like Jupiter and Saturn are believed to have a rocky core. The process of sedimentation of heavy elements may have occurred in the core of giant planets during their formation. The composition of Jupiter's core is similar to that of Saturn and Neptune. They are made up of a rocky core and an icy ring of hydrogen and helium. However, it is not yet clear how these two planets formed.
They have elliptical orbits
The planets' orbits are ellipses, with their distances between their foci being always the same. The eccentricity of the ellipse is a measure of its degree of flattening. The higher the eccentricity, the more distant the planet is from its own star. The eccentricity of a planet's orbit is typically zero, while that of Mercury is higher.
They have a thick atmosphere
The thickness of the atmosphere on a planet is due to a combination of two different processes. Planets that have a thick atmosphere have high amounts of hydrogen and helium. These gases are responsible for the planet's warmth and protect the planet from ultraviolet radiation. On earth, the atmosphere contains many different substances including water and oxygen. Each planet has its own unique atmosphere. The atmosphere of a terrestrial planet is typically heavy and contains more nitrogen, oxygen, and argon than an atmosphere on a rocky planet.
