Extract of sample "Near-Earth Asteroids"

John A Astronomy Assignment 11 July Near-Earth Asteroids The impact hazard linked to newly discovered Near-Earth objects (NEOs) like comets and asteroids can be categorized by the use of Torino scale. According to Yeomans and Chodas of NASA, the Torino scale serves as a communication tool for the public and astronomers to gauge the criticality of collision predictions of any close encounters by the NEOs during the 21st century. The single threat value of collision predictions can be ascertained by combining known kinetic damage potentials and probability statistics.

According to Russ Rowlett of the University of North Carolina, 99942 Apophis Asteroid has reached the highest level on this scale with level 4 only for a brief period in December 2004. This asteroid has an approximate diameter of 270 meters.

Initial observations of the asteroid suggested a small chance (up to 2.7%) that the asteroid may strike earth probably on 13th April 2029. NASA has predicted 1 in 300 chance of the asteroid striking the Earth. But the results may change based on the day to day observations by NASA.

Near Earth Objects (NEOs)

...? In school we hear all sorts of things about asteroids, meteors, and comets. We stay up late to watch meteor showers, and use powerful telescopes toobserve everything in the sky and beyond. While there are plenty of things to observe in deep space, there are also a number of objects that can be found close to the Earth. Some of these objects actually do enter the Earth’s atmosphere. At specific times of the year, meteor showers can be observed, their fiery tails sweeping across the night sky for all to see. Another type of Near Earth Object that can be seen is the comet. Depending on how close they are to the Earth, they can be spotted...

Did asteroids kill the dinosaurs

...? The Mass Extinction of the Dinosaurs: What was the Cause? The Mass Extinction of the Dinosaurs Life on Earth is not always a sure thing for the species who live here. Periodic extinction events, where a large portion of the living species are wiped out, have occurred at least five times since the fossil record of life began, approximately 600 million years ago. The extinction event that is most familiar today is the one which killed off the dinosaurs, and allowed mammals to take their current place as the dominant species type (York 2006). One of the most well-known theories for the cause of this extinction event is an asteroid hit, but there are several others, including global climate change, volcanic...

Planet Earth

...Planet Earth: Disc There are cycles to almost everything in nature and this is shown in the first DVD of the Planet Earth series; "From Pole to Pole/ Mountains/ Fresh Water". The seasons are a cycle that is brought up continuously throughout every section, whether it is two seasons or four depends on the location. Places that reside along the equator experience only two seasons, one wet and one dry, because they get an immense amount of direct sun exposure. This is because of the way the Earth is positioned; this tilt of the earth's axis is also what is directly responsible for the four seasons of the most northern and the most southern climates.

Near Earth Objects

...NEAR EARTH OBJECTS We all know that the gravitational attraction of the earth’s natural satellite, the moon, to our planet causes the sea to rise. However, the moon and its gravitational pull aren’t the only things that cause the face of the earth to change way outside the atmosphere. Comets and asteroids traveling through space have been placed into orbits within the Earth’s neighborhood because of the gravitational pull of nearby planets; these are called Near Earth Objects or NEOs. NEOs are said to have a distance less than 1.3 AU. NEOs are mainly asteroids (called...
