Hello! Now I will share my knowledge about the rest of the solar system which is about the comets, asteroids, and much more! First of all, I will talk about the comets or in other words, shooting stars. The comets are big rocks made of ice and dust, which makes them some sort of dirty snowball. They hurtle through space at relatively high speeds. When a comet is close to the Sun, it moves much faster than when it is farther away from the Sun. Comets also have their own irregular orbit, which is usually oval-shaped. The most famous comet is the Halley’s comet, which makes an orbit around the Sun every 76 years. Comets mainly reside in the Kuiper Belt and Oort Cloud. The Kuiper Belt is a pack of dust, rocks, ice, and comets that orbit the Sun at 30-100 AU (Astronomical Unit), which is further from the Sun than Neptune. Just in case you don’t know, an Astronomical Unit or AU is a measure of length, which is the distance between the Earth and the Sun (150,000,000 kilometers). The O...

Hello! This is part 2 of the Solar System blog! (If you haven’t read part 1 yet, try reading that one first!) Today, I will be talking about the Jovian planets aka gas giants in our solar system! We begin with the fifth planet from the Sun, Jupiter. It’s the biggest planet in the solar system. Even though its mass is more than all of the other planets combined, it still only consists of less than 0.1% of all the mass in the solar system! Jupiter’s most famous feature is the Great Red Spot, a high-pressure hurricane region on Jupiter’s surface. It’s been occurring continuously since it was first spotted by Cassini in 1665. The Great Red Spot is as large as 3 Earths. Jupiter also has over a whopping 60 moons. The most famous are the Galilean Moons, which names are Ganymede, Io, Callisto and Europa. Ganymede is also the biggest moon in the solar system, being bigger than Mercury, having its own magnetic field and atmosphere. Io is a volcanically active moon, spewing out su...

You know about the solar system, don’t you? It belongs to our star, the Sun. The Sun's gravitational pull helps the planets have their orbit. Together, they form the solar system. I will be describing our Sun and planets. The Sun is our star. It gives our planet warmth and life for eons. Some cultures believe that the Sun is a god. It is around 1.5 million kilometers wide. Its surface temperature is around 6000°C but its core can reach temperatures of 15,000,000°C. One day the sun will explode into a white dwarf. When the sun‘s light is blocked out by the moon, it causes a solar eclipse. Plus, the Sun is the reason why there are seasons (along with the earth’s axis), equinoxes, and solstices. Coming up pretty small is Mercury. It is the smallest of the planets. Mercury has barely any gravity and a very thin atmosphere. However, it has scorching temperatures of 430 degrees Celsius and can suddenly drop to a teeth-chattering negative 180 degrees Celsius. It has a year...

When I was younger, sometimes I wonder how magnets work. I played with them a lot. Then I read a book about it and now I finally understand about the magnetic force and energy. I have decided to share this information with everyone. First, as everyone should know, magnets can attract magnetic things such as iron and steel, but not things like aluminum and plastic. Second, two magnets can attract each other as long as their poles are not the same. If they are the same, they will repel. Third, magnets don’t use magic. They use a magnetic field, which I will explain in the next paragraph. A magnetic field is a strong field around a magnet that attracts metallic objects or other magnets. A way to determine what your magnet’s magnetic field looks like is to sprinkle iron powder around the magnet and you should see that the pattern. This pattern is the same as the one in Earth’s magnetic field. There are three types of objects in terms of magnetic force. The first t...
