"Our Universal Address-the Solar System"

"Our Universal Address-the Solar System"," We may live apart in terms of street, city, and even nation, but we all have a common address, the Solar System! How did the solar system come into existence? It is generally believed that it emerged from a gaseous cloud several billion years ago and planets, an important component of the system, were formed out of this gaseous cloud and its dust. It is now a dwarf planet. The Sun is a bright star and exudes heat and light through nuclear fusion. A planet, according to the IAU, is a spherical object that orbits the Sun. Today, there are eight recognized planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Earth's natural satellite is the Moon. The former are rocky, have minerals and metals, have few or no natural satellites, and don't have rings. Dwarf planets are also spherical objects orbiting the Sun, but unlike planets their surroundings don't have to be clear of smaller celestial bodies. Small solar system bodies include asteroids and comets. Asteroids are mainly found in the region between Mars and Jupiter. Ceres is the largest asteroid. Comets that have orbits less than 200 years, such as, Halley's Comet are known as short-period comets, while those with orbits spanning thousands of years are known as long period comets. Technological advances in the form of telescope and spacecraft have helped scientists to obtain a lot of information about the solar system. And you are wrong if you thought only astronomers and scientists looked through the telescope, it's a hobby for thousands of people! . TRY SOMETHING NEW JUST THIS ONCE
