today i am talking about one of the most mysterious thing to us space. We only know small stuff about space so today i'm gonna talk about the things that aren't unknown to us.
The Solar system
our solar system has
8 planets
1.Mercury 2.Venus
3.Earth 4.Mars 5.Jupiter
6.saturn 7.Uranus 8.Neptune
Our solar systems age
is 4568 billion years old.
Mercury Venus Earth
and Mars are mainly made of rocks and metals.
Jupiter and Saturn
are mainly made of hydrogen and helium.
The milky was galaxy
The milky way galaxy is the galaxy that contains our solar system. The galaxy has from 200-400 billion stars. our galaxy is very old its 11682 billion years old scientists say. They say that our galaxy in 4 billion year will colide with another galaxy named the Andromenda and scientists say our solar system maybe ejected from the entire galaxy.
Earth like planets Reaserchers have
discovered the most similar planet yet to earth. It is 1400 light years away
from earth kepler-452b obits its star in 385 days just 20 days longer than our
year. Its star is just 4% larger and a half a billion years older and and its 20%
brighter then our Sun. the kepler-452b is in the goldilocks zone which means
the planet is not to close to its sun so it can be very hot or its not very far
so its very cold its like Earth. There are
more earth like planets for example kepler-182f
kepler-438b kepler-440b kepler-442b kepler-452b etc.
Black holes Black holes are so mysterious thing in space. Black
holes are unstoppable you cant do anything to get away from even if you are
traveling by the speed of light. A black holes only weakness is time. Black
holes can suck in everything even another black hole but it depends its size.
Imagine if a black hole came close to our solar system it will take only
seconds to destroy all of our solar system but black holes sometimes don’t suck
in the planets they turn it to the size of a golf ball.
