    The Planet:

    Perhaps the most common name for most people is the planet, but do you know what actually constitutes a planet and the difference between the exoplanet and the smaller planet, for example?

    The planet is a large chunk of rock or a ball of gas which is large enough to form a sphere because of its gravitational pull, but it is not large enough to begin its nuclear fusion. The planets must also remove their planetary orbits, which is the law that saw Pluto demolished his planet in 2006.

    Definition of Planet by NASA’s International Astronomical Union (IAU):

    NASA’s International Astronomical Union (IAU) officially defines the planet as a celestial body orbiting a star, but it is not a satellite, it is large enough and therefore almost circular, and it removes the orbit around its orbit.

     Dwarf Planet or small planet:

    The difference between a planet and a dwarf or small planet is the area around each celestial body. NASA’s official guide indicates that the planet is called dwarfed or shorter if it does not clear its orbit around its orbit.

    A brand New Dwarf Planet:

    Investigators say they have discovered a brand new planet, orbiting the Pluto across the Kuiper Belt. Named for 2014 UZ224, the object is said to be about 530 km (530km) wide and was seen 8.5 billion kilometers (13.7 billion km) from the Sun.

    If confirmed as a small planet, it will join the most famous vegetable planet in our system, Pluto, along with Eris, Haumea, Ceres and the newly discovered Makemake. The 2014 UZ224 is the third most distant feature in our system, after Eris, and V774104, which was released in October.

     Exoplanet

    The exoplanet is simply the planets that orbits the star outside the Sun, outside of our solar system. The newly discovered Proxima b is a model of exoplanet and astronomers believe it has the right temperature for liquid water to be present on its surface, suggesting that alien life could be found on a rocky surface much larger than Earth.

    To make this finding, researchers saw Proxima Centauri using a Harps spectrograph and an 3.6-meter-long ESO telescope at La Silla in Chile, while others also observed the closest star to Earth, outside the Sun, as part of the Pale Red Dot Campaign.

    The cool, bright red star (scroll down for a reddish definition) is part of the third star system at the Alpha Centauri solar center, approximately 25.2 trillion miles from Earth and also the target of the first human effort to go to another star system, the Starshot project.

    Cosmic dust:

    Cosmic dust mainly contains silicon, carbon and aluminum, all made by internal stars. The elements are scattered throughout the universe when the stars die. Now, because so many stars have been born and died, there is a tremendous amount of dust. It is also an important part of the creation of stars and planets.

    Brown Dwarfs:

    One step further in size gives us brown dwarfs, which are not big or hot enough to kick their junctions, so they cannot be called stars, but are larger than planets. Commonly described as a planet-star hybrid, brown dwarfs tend to be between 13 and 80 Jupiter.

    The Stars:

    The stars begin their life as scattering clouds of wind and dust known as nebulae, which combine slowly with gravity.

    They can spend most of their lives anywhere between the size of 0.08 and 300 the size of our solar weight. A common feature among all of them, however, is that they are all major nuclear compounds, with the combination of their ancestry making their existence possible. In the smallest stars, hydrogen is converted into helium, and the larger, hotter stars are able to combine larger objects together.
