Hermes Asteroid Accretion

This how Hermes Asteroids formed. Gas and Dust collect in a nebula. Particles start to join together. Small objects form through accretion. After that the Asteroids start to form. Large objects cant accrete because the gravity of Jupiter and Mars pull at them. Now they exist in an Asteroid Belt of small objects and cant become planets.

Vocab

accretion- when two objects collide and make a bigger object.

fussion- when atoms collide and fuse together.

plasma- a state of matter that is hotter than gas and more dense then solids

supernova-an explosion that produces star.

Why Pluto is not planet

Pluto is no longer considered a planet. It was once considered a planet a while ago. It is no longer considered a planet because it no doesn't fit the "rules" to be a planet. In order to be considered a planet, you would have to be a sphere, have enough gravitational pull to govern all the objects around it, which would clear the orbit, and it would have to orbit a star. Pluto does not have enough gravitational pull to govern the objects around it. Scientist have recently discovered that Pluto can not clear its orbit. It keeps crashing into different objects. My body is not considered a planet. It isn't planet because it does not fit any of the concepts in being a planet. It is an asteroid. Since it is an asteroid, it is not a perfect sphere. It does not orbit a star. It is on the asteroid belt, which orbits between Mars and Jupiter. It can't clear its path because it doesn't have gravity.

What did we do in each exhibit?
We saw a movie. In the building we walked down the cosmic pathway. It had different years of events from 13 million years ago to today. During the movie, it showed us how the universe was like one second after the Big Bang Thoery. It also explained how the universe different then it was an hour after the Big Bang then today. In the Rose Center we went to the Cullman Hall of the Universe. In the Cullman Hall of the Universe, they had exhibits on planets and asteroids, meteres, meteroites, etc.

3 things that i learned:
1. After the Big Bang the Earth remained dark for several million years
2. Most of meteroites that hit Earth are wayward fragments from the asteroid bolt.
3. Meteroites provide information on the history of our solar system, we can learn details about how our solar system envolved into the sun and planets of today.

2 questons:
How old is my body?
What can we predict something about a meteor by just looking at it?

Discovery- Hermes Asteroid

Hermes Asteroid was first discovered in 1937. It disappeared for 66 years and then found again on october 15. It was discovered by arecibo's telescope. At first they thoguht it was just a bright object passing by. But it is actually two giant objects in space traveling together. Hermes makes frequent close approaches to Earth, Venus, and Mars. It is the third biggest asteroid in the asteroid belt between mars and jupiter.
