Freak Asteroid With Six Amazing Tails!
by
Judith E Braffman-Miller
Asteroids are relatively small, rocky-metallic relics left over from our primordial Solar System, that formed about 4.56 billion years ago. In November 2013, astronomers announced that after observing our Solar System's Main Asteroid Belt with NASA's venerable Hubble Space Telescope, they had viewed, for the very first time, a freakish asteroid sporting six comet-like tails composed of dust, streaming behind it. This weird asteroid, dubbed P/2013 P5 resembles a familiar rotating lawn sprinkler--and its bizarre appearance is extremely puzzling!

A Trojan Asteroid Haunts A Distant Ice-Giant Planet
by
Judith E Braffman-Miller
Asteroids are the lingering relics of the original primordial building-blocks of the four inner rocky planets--Mercury, Venus, Earth, and Mars--that populated the early Solar System, born about 4.6 billion years ago. These rocky remnants of our Solar System's past now occupy a region between the planets Mars and Jupiter in what is called the "Main Asteroid Belt." However, not all of the asteroids occupy this Belt. "Trojan" asteroids are a vast population of bodies that swarm around our Sun within the same orbits as the giant planets of the outer Solar System, primarily Jupiter. In August 2013, astronomers from Canada and France announced that they had spotted the very first Trojan asteroid known to share its orbit with the blue-green, ice-giant planet, Uranus--the seventh planet from our Star, the Sun.

Asteroids are slighter version of planets. These are called planetoids that orbit around the sun. Asteroids might be larger as compared to meteoroids, however small compared to planets.

Asteroids - Are They Dangerous?
by
Felipe Faria
There is a lot of exciting things happening in the stars above us which make astronomy so enjoyable. The truth is the universe change regularly, moving, some would say "living" thing simply because you never determine what you're going to see on any given night of stargazing. But of the numerous celestial phenomenons, there's probably none as exciting as that time you observe your first asteroid traveling in the heavens.

Wild Horse Asteroids
by
Judith E Braffman-Miller
Trojan asteroids are a large group of objects that swarm around in the same orbit as the gas-giant planet Jupiter. Like wild horses, the asteroids gallop through space in herds, with one swarm leading the way in front of Jupiter, and a second swarm trailing behind. But where did the Trojans come from? Astronomers using data obtained from NASA's Wide-field Infrared Survey Explorer (WISE) have now uncovered new clues pertaining to the mysterious origin of these asteroids!

Bringing Home The Asteroid
by
Judith E Braffman-Miller
Asteroids are lingering remnants of our primordial Solar System, which was born about 4.6 billion years ago as a result of the gravitational collapse of a small, dense, glob embedded within a cold, dark, giant molecular cloud. In April 2013, NASA announced a new, audacious, and somewhat ingenious and ingeniously daring plan to lasso an asteroid and pull it back to Earth's Moon so that astronauts could visit it in the future.

Can We Stop a Spinning Asteroid or Slow it Down to Dock a Space Craft On It?
by
Lance Winslow
Trying to land on an asteroid may not be as easy as you think, many of these asteroids spin at very high speeds. Therefore, to land on one the spacecraft needs to get along side of it and spin around with it at the same rate. That might be impossible considering that we know the there are laws of physics concerning these things.

Killer Asteroids - Lessons From Asteroid TC3
by
Ian Maclean
The discovery of Asteroid TC3 2008 and its subsequent impact above Sudan was a free kick for planetary defense. The probable Impact of a Meteorite in central Australia just a week later was a reminder of the real threat we face from Asteroids and Comets. This article explores what we know, what we can and are doing about these rouges from deep space.

Comets Cruise the Solar System Until they Collide or Evolve and Decay Into Main Asteroid Belt
by
Lance Winslow
Generally speaking, scientists believe that comets go round and round the solar system until they run into something, something big like a planet. Although recently we have noticed that some asteroids and comets end up hitting each other, when they do - both of the courses are altered. And sometimes one or both are completely destroyed due to the impact.
