<p dir="ltr">Even from the past, people were already fascinated by this huge expanse of universe. The solar system, abundant with many celestial bodies, offers a tremendous opportunity for discoveries and explorations. Starting from planets and their moons to asteroids, comets, and meteoroids, all narrate unique sagas to mankind regarding the origin and evolution of our cosmic vicinity. From here, it's an enjoyable journey through our solar system, great for adults but for kids, it's intriguing space exploration. We are going to explore: what interesting things are in the night sky, try to understand what exactly different celestial bodies are about, and observe the ways they impact the Earth. Spotlighting some famous space rocks and significant finds will be done in the process.</p>
<h2 dir="ltr">Introduction to the Solar System</h2>
<p dir="ltr">The solar system epitomizes a complex and dynamic ensemble of celestial bodies orbiting our Sun, comprising eight major planets, many moons, dwarf planets, asteroids, comets, and meteors. All these bodies have very special features of their own and participate in the subtle dance of our cosmic environment.</p>
<ul>
<li dir="ltr" aria-level="1"><strong>Solar System Planets:</strong> The eight planets of the solar system are basically grouped into two: terrestrial planets and gas giants.</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation"><strong>Terrestrial Planets: </strong>Mercury, Venus, Earth, and Mars. These planets are composed primarily of rock and metal and have solid surfaces.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation"><strong>Gas Giants:</strong> Jupiter and Saturn. These giant planets consist mostly of hydrogen and helium.</p>
</li>
<li dir="ltr" aria-level="1">
<p dir="ltr" role="presentation"><strong>Ice Giants: </strong>Uranus and Neptune. These planets are made up mostly of water, ammonia, and methane ices.</p>
</li>
</ul>
<h3 dir="ltr">Constellations</h3>
<p dir="ltr">Constellations are patterns of stars in the night sky, recognized and identified by various cultures over time and named as such. They are a means of orientation in the sky and provide context to understand the position and movements of celestial bodies within the solar system.</p>
<h2 dir="ltr">What are Asteroids, Comets, and Meteors?</h2>
<h3 dir="ltr">Asteroids</h3>
<p dir="ltr">Asteroids are rocky, airless remnants left over from the formation of our solar system. Most are located in the asteroid belt between Mars and Jupiter, although they can be found throughout the solar system. They run in size from tiny pebbles to hundreds of kilometers in diameter. The largest asteroid, Ceres, is also classified as a dwarf planet.</p>
<h3 dir="ltr"><strong>Comets</strong></h3>
<p dir="ltr">Comets are ice bodies from the outer solar system. As they approach the Sun, their ice vaporizes, creating a glowing coma with quite often a spectacular tail. Comets consist mainly of water, carbon dioxide, methane, and ammonia mixed with dust and rocky material.</p>
<h3 dir="ltr"><strong>Meteors</strong></h3>
<p dir="ltr">Meteors, otherwise called "shooting stars," are streaks of light one sees when a meteoroid enters Earth's atmosphere and in the process, goes out in contact with air friction. In the event that the meteoroid stays intact during this process of passing through Earth's atmosphere, landing on Earth, it is then referred to as a meteorite.</p>
<p dir="ltr"><img src="https://cdn-cms.orchidsinternationalschool.com/media/new-astro.jpg" alt="Meteors" width="708" height="472"></p>
<h2 dir="ltr">How Do These Celestial Bodies Impact Earth?</h2>
<h3 dir="ltr"><strong>Asteroids and Earth</strong></h3>
<p dir="ltr">Asteroids have hit Earth since the latter's beginning. While most asteroids are too small to do any harm, bigger ones may be devastating. The most famous example is the asteroid that hit Earth 65 million years ago, causing the extinction of the dinosaurs.</p>
<h3 dir="ltr"><strong>Comets and Earth</strong></h3>
<p dir="ltr">Comets have also played a part in the history of Earth. It is believed that they brought water and organic compounds to our planet, and therefore they participated in establishing life on Earth. Just like asteroids, though, comets can be dangerous in case they fall on Earth.</p>
<h3 dir="ltr"><strong>Meteors and Earth</strong></h3>
<p dir="ltr">Meteors are pretty harmless because they break up in the atmosphere. But larger meteorites can cause damage if they actually make it to the surface. Probably the most significant recent event was the Chelyabinsk meteor explosion over Russia in 2013 that caused great damage and injuries.</p>
<h2 dir="ltr">What Other Planets Can Teach Us About Earth</h2>
<p dir="ltr">Other planets in the solar system have much to say about our past, present, and future. Through them, many processes that have taken place on the Earth can be explained by scientists and go on to predict future changes.</p>
<h3 dir="ltr"><strong>Mars: The Red Planet</strong></h3>
<ul>
<li dir="ltr" aria-level="1">

</li>
</ul>
<h2 dir="ltr">Famous Space Rocks and Their Discoveries</h2>
<h3 dir="ltr">The Chicxulub Crater</h3>
<p dir="ltr">The Chicxulub Crater in Mexico is believed to be the impact site of the asteroid that caused the mass extinction of the dinosaurs. This discovery has provided valuable insights into the effects of asteroid impacts on Earth's environment and evolution.</p>
<h3 dir="ltr">Halley's Comet</h3>
<p dir="ltr">Halley's Comet is one of the most famous comets, known for its regular appearances every 76 years. It has been observed and recorded by various cultures for millennia, providing important data about the composition and behavior of comets.</p>
<h3 dir="ltr">The Tunguska Event</h3>
<p dir="ltr">The Tunguska Event in 1908 was caused by the explosion of a meteoroid or comet fragment over Siberia, flattening an estimated 2,000 square kilometers of forest. This event highlighted the potential danger of smaller celestial bodies and the need for monitoring near-Earth objects.</p>

<h2 dir="ltr">FAQS&nbsp;</h2>
<h3 dir="ltr">Why do we study other celestial bodies?</h3>
<p dir="ltr">Scientists since Galileo have sought to understand other planetary bodies through an earthly lens. More recently, researchers have recognized planetary exploration as a two-way street. Studies of space have helped to explain aspects of climate and the physics of nuclear winter, for example.</p>
<p dir="ltr">&nbsp;</p>
<h3 dir="ltr">What is the only celestial body humans have visited?</h3>
<p dir="ltr">The Moon is also the only celestial body besides Earth that humans have visited.</p>
<p dir="ltr">&nbsp;</p>
<h3 dir="ltr">Have we visited other planets?</h3>
<p dir="ltr">Despite amazing progress in space travel, humans have been unable to travel to other planets. We have, however, been able to send rovers to the surface of one of our planetary neighbors: Mars. Sojourner&mdash;named for the 19th century abolitionist who fought for women's rights&mdash;was the first successful Mars rover.</p>
<p dir="ltr">&nbsp;</p>
<h3 dir="ltr">Is there another Earth with humans?</h3>
<p dir="ltr">The Moon is the only other place humans have visited. No other planet in our solar system currently has the conditions to support life as we know it on Earth.</p>
