- Neptune is the final outer planet in the solar system. Neptune’s winds are the fastest of any planets in the Solar System and can reach more than 1,200 miles per hour. While all of the outer planets’ atmospheres contain hydrogen and helium, Neptune and Uranus contain significant amounts of what astronomers call ices. These ices include water, ammonia, and methane. The methane in Neptune and Uranus is what gives the planets their blue color.

- The four planets closest to the Sun are largely made up of rock, like the Earth, and are called the terrestrial (Earth-like) planets. The next four planets are much larger and made mainly from hydrogen and helium. They are often called gas giants.Pluto is different still, a deep-frozen world of rock and ice.LANETS. A planet is a world that orbits a star. There are nine planets circling around the Sun—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. They take different amounts of time to orbit the Sun, from only 88 days for Mercury to nearly 250 years for Pluto.

Comet Facts Comet Facts. Comets, like asteroids, are small celestial bodies that orbit the Sun. However, unlike asteroids, comets are composed primarily of frozen ammonia, methane or water, and contain only small amounts of rocky material. As a result of this composition comets have been given the nickname of dirty snowballs..

Comet This article is about the astronomical objects. For other uses, see Comet (disambiguation). A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles.

Our Solar System The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has.

- The outer layers of these planets are made up of hydrogen and other gases. So the Sun is the collapsed core of an interstellar gas cloud, and the planets, asteroids and comets are small lumps of dust or ice chunks which stayed in orbit instead of spiraling into the Sun. The planets all formed within a very short period, probably a few million years, about five billion years ago.

Glossary As a result, the gland can't make enough thyroid hormone. Other things that can lead to low levels of thyroid hormone include surgery to remove the thyroid gland and radiation therapy for cancer. Less common causes include viral infections and some drugs, such as amiodarone and lithium.t makes hormones that control the way your body uses energy. Having a low level of thyroid hormone affects your whole body. It can make you feel tired and weak. If hypothyroidism is not treated, it can raise your cholesterol levels.

Why do space objects like meteors, asteroids, and comets travel so fast? Everything Earth can encounter (and collide with) in the solar system is falling towards and/or around the Sun. This is a simple result of how gravity works. When an object (stone, comet, planet, etc...) is falling around the Sun, we call it 'orbiting'.

Planets and How They Formed Planets and How They Formed. The planets in our Solar System are believed to have formed from the same spinning disc of dust that formed the Sun. This disc, called the solar nebula, was composed mainly of hydrogen and helium, but also had other elements in smaller proportions.The nebula had a certain amount of angular momentum orbiting the forming Sun. Particles in the spinning disc began to clump together as gravity attracted them to each other.hese larger objects, about the size and mass of our Moon, are called protoplanets. The accumulation of material to form planets in this way is called accretion. The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous.

Space Environment Besides nebulae and interstellar dust, there are also bits of rubble as big as small moons to as small as grains of sand. These bits of rubble are called planetoids and asteroids. Radio, heat, and x-rays all echo through space, as do beams of light. There is radiation bursting forth in solar flares. The Orion Nebula.

What Is the Sun Made Of? The sun is a big ball of gas and plasma. Most of the gas — 91 percent — is hydrogen. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light. Nuclear fusion. In the sun's core, gravitational forces create tremendous pressure and temperatures. The temperature of the sun in this layer is about 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion. As the gases heat up, atoms break apart into charged particles, turning the gas into plasma.

Comet Comet: Comet, a small body orbiting the Sun with a substantial fraction of its composition made up of volatile ices. When a comet comes close to the Sun, the ices sublimate (go directly from the solid to the gas phase) and form, along with entrained dust particles, a bright outflowing atmosphere around the comet nucleus known as a coma.

Comet Facts Facts about comets. 1  Sometimes comets are referred to as “dirty snowballs” or “cosmic snowballs”. This is because they are composed mostly of ice, rock, gas and dust. 2  Comets orbit the Sun in elliptical paths – just like the planets. The path of a comet though is far more elliptical than that of any planet.

The Solar Wind If a planet has a magnetic field, it will interact with the solar wind to deflect the charged particles and form an elongated cavity in the solar wind. This cavity is called the magnetosphere of the planet. In the vicinity of the earth, the particles of the solar wind are traveling about 400 km/s.They are slowed by the interaction with the earth to produce a bow shaped shock wave around the earth. Inside a boundary called the magnetopause, the earth's magnetic field is dominant over the effects of the solar wind.The small fraction of the charged particles which do leak through the magnetopause are trapped in two large doughnut-shaped rings called the Van Allen radiation belts.n the vicinity of the earth, the particles of the solar wind are traveling about 400 km/s. They are slowed by the interaction with the earth to produce a bow shaped shock wave around the earth.

What's in the heart of a comet? Here is what scientists have found out. Comets are part of the solar system. They orbit the Sun, just as planets do, except a comet usually has a very elongated orbit. Part of its orbit is very, very far from the Sun and part is quite close to the Sun.A comet's nucleus is like a dirty snowball made of ice.As the comet gets closer to the Sun, some of the ice starts to melt and boil off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma.ere is what scientists have found out. Comets are part of the solar system. They orbit the Sun, just as planets do, except a comet usually has a very elongated orbit. Part of its orbit is very, very far from the Sun and part is quite close to the Sun.
