Comet and Astroid

Dyllan Baranchak

Comets

  • Comets are big chunks of rock and ice left over from the formation of stars and planets
  • Comets form when planets were
  • comets formed about 4.6 billion years ago
  • They are formed outer parts of the solar system
  • Comets and planets both orbit the sun
  • They both follow Kelper's law where the closer they get to the sun the quicker they move
  • Planets orbit in more of a circular pattern around the earth while comets orbit in a vertical elliptical pattern
  • Comets have tail when they are by the sun
  • The ice melts due to the suns heat it produces a tail of water vapor, gas, and dust
  • When a comets is visible from earth it looks like a rock
  • Comets that are seen through through telescopes look like shooting stars

Rosetta's comet

The bright object in the middle of the picture with a tail like trail is the comet rosetta. It was taken using a machine named ESO VLT, which is a very big telescope.

Video summary

The comet ISON is disposing 112,00 pounds of dust every minute. If it keeps in its orbit and disposing dust, the earth will run into the dust showers. The dust is very small and will not harm anything. There may be notilucent clouds. Notilucent clouds are clouds that are high up and very luminous at night.

Asteriods

  • Asteroids are also rocky metallic objects that can be as big as 600 miles around and can be as small as pebbles
  • A meteor is the flash of light while a meteorite is the debris
  • An asteroid is just a large chunk of rock
  • A near earth astroid is an astroid that has been pulled by gravitational forces into a nearby planets orbit, which makes them earth neighbor
  • A historical asteroid event was 65 million years ago and caused global warming, a global firestorm, and a cold snap to extinct the dinosaurs

Vesta is the brightest and the second biggest asteroid. Picture was taken by a space satellite.

News article

This news article is written by the new york times. It is about how more asteroid strikes are possible. A asteroid hit aRussian city in February 2013. Also people are not comfortable with this threat of asteroid strikes. Sentinel is a telescope that will find asteroids near earth that are 450 feet wide. Planetary is a term used when something is related to planets.
