About Space
The Sun is more than 3,00,000 times larger than the size of the earth, which means 1 million Earths could fit inside the sun.
Space is absolutely silent as there’s no atmosphere for sound to travel through.
There are more stars in the universe than there are grains of sand on Earth.
It is believed that there are between 200-400 billion stars just in the Milky way galaxy. Our solar system is a very, very tiny part of it.
In the observable universe, there are about 100 billion galaxies like the Milky Way. There could be around 100 billion Earth-like planets in our galaxy alon.
If you say highest mountain known to man is Mount Everest, you are partially correct. Mount Everest is the Highest mountain on Earth, but the highest mountain known to man is actually present on an asteroid called Vesta and is 22km in Height, thrice as big as Everest.
Venus is the hottest planet in the solar system and has an average surface temperature of around 450C. Interestingly, Venus is not the closest planet to the Sun.
Mercury is closer but because Mercury has no atmosphere to regulate temperature it has a very temperature fluctuation.
Space Facts
it’s all Relative. The Earth is 8000 miles across, and that is big, compared to us anyway. Let’s put it inti perspective and take a look at how we compare as a player. To start with, our Moon is 250,000 miles away from the earth. That means that there is enough space in between the earth and the Moon to fit in an extra 30 planets the same size as earth. Most planets in our solar system are much bigger than us.
Recently a meteorite crashed into Jupiter. Scientists estimate that the mark that it left is the same size as the Earth. Take a look at the vide of the meteorite crashing. Look carefully because it is hard to spot. But if you thought Earth is big our Sun is 850,000 miles across. That’s over 100 times bigger than the earth.
light year in Space
What do you know about the universe? Well, it’s sort of big right? It’s not just big- it’s really, Really Big. The reason why it’s hard to see how big stuff is because it is so far away. Everything looks small to us because its millions and billions and trillions of miles away. The problem scientists have is that describing distances in miles or kilometers becomes meaningless there are just too many 0000000000000’s. We need a much bigger unit. This is called the light year. A light year is how far light can travel in year.
How Much Space in Space
Light travels at 186,000 miles per second, the speed limit for universe. So, in a year a ray of light covers about 6 trillion miles. Think about it this way- in one second light can travel round earth 7 times. Imagine how far it gets in a year. The nearest star to our Sun is Proxima Centauri. This star is four light years away – about 24 trillion miles. Our Galaxy, the Milky way, is about 100,000 light years across/ Even travelling at the speed of light it would take 100,000 years to fly from one side to the other.
Galaxies
Scientists think there might be as many as 500 billion galaxies and that is just too big to think about. The most distant galaxy scientists have ever seen is 13,000,000,000 light years away. So the furthest away visible galaxy is 78,000,000,000,000,000,000,000 miles away. When you see stars and galaxies in the sky, you are seeing what they looked like billions of years ago. In fact, when you look up at the stars, some of them actually no longer exist. They will have disappeared centuries ago, but their light is still travelling to us.
Space Planets
Consists of things such as planets, moons, asteroids, comets, meteoroids and other interstellar matter. The Solar system was form over four and a half billion years ago.
the nine planets that constitute the Solar System are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
It was only recently humans came to be aware of the Solar System. Unite then, It was believe that earth was to center of the Universe. Famous Astronomers such as Copernicus, Galileo, Newton, and Kepler helped develop modules that explained the solar system, sun and the movement of planets.
While the Sun makes up about 99.85 percent of the total mass of the Solar System, the planets Jupiter and Saturn make up the rest. The smaller remaining planets constitute an exceedingly small percentage.
