Journey Around the Solar System



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 of 88 Earth days and a sidereal day of 59 Earth days. But thanks to its orbit, it has a whopping solar day length of 176 earth days!

Next is scorching hot Venus. It is named after the roman god of beauty, but when you research Venus, it is definitely not beautiful. It has a runway greenhouse effect, causing the temperatures to rise to a dazzling 467 degrees Celsius. Good thing is, you can spot Venus in the east at almost every dawn!

Now for our home planet Earth. You should know most of the information about Earth by now, but just in case you forgot, a day on Earth lasts 24 hours and a year lasts 365 days. It has a diameter of 12.000 km and has a circumference of 40.000 km. It lies approximately 150 million km from the sun.

Last but not least, Mars. It may as well be our next home planet as Earth is suffering from rising temperature. Long time ago, Venus and Mars looked similar to Earth, but Mars was too far away, while Venus was too close. It has sub-zero temperature so if anyone finds water on Mars; it’s going to be in the form of ice. Plus, Mars barely has any oxygen and its atmosphere contains mainly carbon dioxide. The main problem is that Mars doesn’t have a magnetic shield to protect us from the Sun’s harmful ultraviolet rays.

That’s all for part 1! If you have any ideas of anything I should add, tell me in the comments section below! I’ll be making part 2. It will be about gas giants and the rest of the stuff in the solar system. I promise you, it’s going to be FUN!

Thanks for reading!

Vectors and Scalars

Image
I want to talk about Vectors and Scalars . This is about physics. Now you might be asking, what is a vector? Vectors have a magnitude and direction. In case you don’t know, magnitude is the size of the movement, but it’s not distance. Since it’s a vector quantity, it’s called displacement .  For example, the displacement of a leaf being blown by the wind is 50 centimeters to the east. This is a vector quantity because it has a magnitude (50 cm) and a direction (east). And there’s more...  If someone asks you the version of speed in a vector quantity, it’s called velocity .  For example, the velocity of a ball being thrown is 5m/s to the east. In other words, five meters per second to the east.  You can find the displacement as long as you have the velocity and time. Multiply them and you will get the displacement. If the velocity is 5m/s and the time is 10 seconds, you need to multiply them ( 5 x 10 ) to get the displacement, which is 50 meters.  A...

Cheryl's Birthday Problem (from SASMO 2015) and Solution

Image
Hello! Nat here, and in this blog, I am going to discuss and give the solution to the famous Cheryl birthday problem. This was popular because it is a difficult logic puzzle and involving the ability of carefully tracking down hints in the conversation and working with only a small amount of data. Here’s the question: Albert and Bernard just became friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of 10 possible dates. May 15           May 16           May 19 June 17          June 18 July 14           July 16 August 14       August 15       August 17 Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively. Albert: I don’t know when Cheryl’s birthday is, but I know that Bernard doesn’t know too. Bernard: At first I don’t know whe...

Black Holes

Image
Black Holes are holes in space that absorbs anything in their way, even stars. They are made by a star exploding as supernova and the star must be about 3 times the mass of the sun. This is called the Oppenheimer-Volkoff limit.  Its core will collapse into a neutron star, but its gravity is so strong that it starts sucking in material from outer space and later turns into a black hole.  Once they absorb enough matter to become powerful and massive, they can start creating galaxies. That is why black holes can be found in the heart of galaxies.  Sometimes, black holes will emit the brightest light waves in the universe – quasars.  Now you might be asking, why don’t we see like “blink, blink” from earth? The answer is that they are very far. The furthest quasar from us is about 14 billion light years away. However, we are lucky to be on a planet that isn’t near a black hole. If we were near a black hole, we would get our atmosphere stripped first then ...
