Venus

Planet

Venus is a terrestrial planet. Venus is the hottest planet in the solar system, why not Mercury? That’s because Venus doesn’t have an ozone layer so the heat that enters the planet is trapped there and won’t come out. Venus is the second closest planet to the Sun after Mercury. Venus has no natural satellites. Venus is almost the same size as Earth, humans call it Earth’s twin because no ther planet has it. Venus is a very extreme planet, it has a avery thick and very poisonous atmoshphere made of carbon dioxide. It’s not over yet, Venus has very thick and very poisonous clouds, the clouds in Venus can also produce sulfuric acid rain which will make you seriously injured if hit. This planet has a very large greenhouse effect, there is global warming everywhere. It sounds like Earth but in the apocalypse version. Breaking news! A few months ago, humans discovered phosphine in a Venus. phosphine is a substance that can only be produced by living things.

Status

Venus has a surface area of 460.2 million km².

Venus has a mass of 4.867E24 kg.

Distance from the sun: 0.7 AU (astronomical unit)

Venus takes 243 days on Earth for 1 rotation (spin on its axis).

Venus takes 224.7 days on Earth to complete 1 orbit around the sun.

Venus does not rotate sideways, but Venus rotates upward. Venus doesn’t actually rotate but spin on its axis. Venus rotates so slowly that it makes its shape almost completely spherical.

Mercury

Planet

Mercury is a terrestrial planet. Mecury is the smallest planet in the solar system. Mercury is also the closest planet to the sun. Because Mercury is very close to the sun, Mercury has a fairly fast revolution time. Mercury has a surfaces made of rock and has a large number of craters. Mercury has neither an atmoshphere nor a moon. Mercury is not only gray, but Mercury has many colors such as orange, dark blue, yellow and many more. However, this color is not very visible because it is very far from Earth and has a dominant color, namely gray. The invisibility is also influenced by the Earth’s atmoshphere which makes it very difficult for us to see other celestial bodies. Mercury is a simple planet.

Status

Mercury has a surface area of 74.8 million km².

Mercury has a mass of 3.285E23 kg.

Distance from the sun: 0.4 AU (astronomical unit)

Mercury takes 59 days on Earth for 1 rotation (spin on its axis).

Mercury takes 88 days on Earth to complete 1 orbit around the sun.

Mercury rotates very slowly but revolves quickly. Even Mercury takes several revolutions to complete 1 day, from morning to night then to morning again.

Nebula

Definition

Nebula is a cloud between the stars in outer space. Nebula are made of dust, gas, helium, hydrogen, and plasma. Nebula can be formed from remnants of supernova, stars that have collided with cold objects, stars that have died, and other amazing events. The Nebula has a very beautiful color and a very unique shape. Nebula can make new stars from the squeezed gas, dust, helium, hydrogen, and other substances that create a center of gravity. The longer it gets denser, heavier and gets hotter until it forms a star.

Size

The nebula is extremely large, its typical size being 9,460,800,000,000 kilometers. Imagine how big the Nebula is and how many stars are there in the Nebula.

Jovian planet

Definition

Jovian planets is a huge planet made of gas. We call it the outer planets. Gas planets have very deep centers and are usually made of metalic or rock. This gas planet has a mass which is mostly hydrogen, helium, water, methane, ammonia, and many more. These gas planets have a very large size, with this very large size they have so much gravity that they can make you weigh 5 times heavier or even bigger. Gas planets have many moons, some have tens of moons to hundreds of moons. Gas planets are very cold because they are so far from the sun, their temperatures can reach more than – 200 degrees celcius. All the gases planets have a ring around it, some are visible and some are not.

Jovian planet:

  1. Jupiter
  2. Saturn
  3. Uranus
  4. Neptune
Jupiter - Wikipedia bahasa Indonesia, ensiklopedia bebas
Jupiter is the fifth closest planet to the sun in the Solar system, Jupiter is also the largest planet in the Solar system.

How Saturn Works | HowStuffWorks
Saturn is the sixth closest planet to the sun in the Solar system, Saturn is also the most beautifull planet in the Solar system.

Uranus - Wikipedia bahasa Indonesia, ensiklopedia bebas
Uranus is the seventh closest planet to the sun in ther Solar system, Uranus is also the coldest planet in the solar system.

Neptune is the eighth planet closest to the sun in the Solar system, Neptune is also a planet full of geysers in it.

Terrestrial planet

Definition

A terrestrial planets is a planet whose surfaces is usually made of rock and metal. We call it the Inner planets. The Inner planets are a small planet, but this small planet is solid and has a very hot core. The Inner planets core are usually made of metal. These Inner planets are also the 4 planets closest to the sun. These Inner planets also contain volcanoes, craters, mountains and canyons. There are 4 planets that exist in the Terrestrial planets. Terrestrial planets with Jovian planets have one seperation, their name is the asteroid belt that lies between Mars and Jupiter.

Terrestrial planet:

  1. Mercury
  2. Venus
  3. Earth
  4. Mars

Mercury is the closest planet to the sun in the Solar system, Mercury is also the smallest planet in the Solar system.

Venus - Wikipedia
Venus is the second closest planet to the sun in the Solar system, Venus is also the hottest planet in the Solar system.

Earth - Canada.ca
Earth is the third closest planet to the sun in the Solar system, it is also the only planet known to have life.

Mars - Wikipedia
Mars is the fourth planet closest to the sun in the Solar System, Mars is also the closest planet to the asteroid belt.

Solar System

Definition

The solar system is a collection of celestial bodies that have a center with a high gravity so that they can attract surrounding objects called stars ad object around them called planets. We have 1 star in our solar system, that star is called Sun. In this solar system we have 8 planets, these planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Planets

We have 2 kinds of planets in this solar system, the first one is a Terrestrial planet, a Terrestrial planet is a planet that has a solid surfaces and its contents are mostly rocks. The second one is the Jovian planet, the Jovian planet is a lanet that has no surface and its contents are mostly gas.

Terrestrial planet:

  1. Mercury
  2. Venus
  3. Earth
  4. Mars

Jovian planet:

  1. Jupiter
  2. Saturn
  3. Uranus
  4. Neptune

There are 3 stages of asteroids in the Solar system, the first is the asteroid belt, the second is Kuiper belt, the third is the Oort cloud.

Asteroid belt

The asteroid belt is an asteroid that seperates the Terrestrial planets and Jovian planets. The asteroid belt lies between Mars and Jupiter.

Kuiper belt

Kuiper belt is a collection of asteroids and ice that lies outside of Neptune and has a lot more asteroids that the asteroid belt. Kuiper belt is usually called the Trans Neptune.

Oort cloud

The sun has very strong gravity so that it can form an area called the Oort cloud. Oort cloud is so far away that it took 30000 years at a speed of 71,000 km/h to get out of the Oort cloud. Oort cloud contains several dwarf planets and 8 billion asteroids outside the Kuiper belt. Far from the sun to the end of the Oort cloud is equal to the distance from the sun to Pluto multiplied by 1000.

Mass

99.86% by mass of the Solar system is the mass of the Sun. While the 0.14% are planets, dwarf planets, comets, asteroids, and gas around the solar system.

Gravity

With these 8 planets, our Solar system is perfectly balanced by the gravity of each planet. So if one planet is removed from the Solar system, that balance will be destroyed and will make all the planets swallowed up into the sun.
