Interplanetary Dust and Orbital Debris

According to NASA, the amount of pieces of space debris currently orbiting the Earth numbers in the hundred-thousands. This vast array of inoperative man-made objects has accumulated over several decades of space travel and exploration and has come from a variety of sources. The majority of space debris in orbit consists of defunct satellites or fragments left behind from collisions between satellites or explosions that were caused by unused fuel remaining in the tanks of defunct satellites. A fraction of the space debris also comprises of rocket stages and other launch hardware. NASA and the US Department of Defense put in a considerable amount of time and energy into tracking and cataloguing such space debris that orbits the Earth. This begs the question: why is the issue of space debris so important?

Identify and describe the components and structure of our Solar System. Include important facts and figures.

Although Stardust was created from Hydrogen, and most of the universe is Hydrogen, one must remember that our planet, our race, and ourselves were created from the other elements that arose afterwards in stars. So one could conclude that just as we were made from Stardust; Stars were made from Big Bang dust. We are connected to the objects created a bit after the origin of existence. A very majestic truth in

Today, the number of satellites to ever launch into space is about 7,500 (Urry, 2014). The number of space debris identified by NASA is over millions of all sizes (“SciTechTalk”). The satellites and particles in the Low Earth Orbit are of greatest concern to scientists because this is where most of the operational satellites orbit around (Jessa, 2011).

In this report, I will explaining the properties of objects in our solar system and how they are grouped. Before this investigation, I had barely any knowledge about the properties of planets and objects in our solar system, but I learned valuable information through research from different websites, and discussions within my group and my entire class. My report will answer the question, “How can we group objects in the Solar System according to their properties?”

We have been given this neat display as a result of the Swift-Tuttle comet’s unusually close encounter with the third planet of the solar system, causing it (this third planet) to pass through a thin, cylindrical-shaped trail of rocky particles such that many burn up in the Earth’s atmosphere, creating a dazzling display of cosmic destruction.

Jupiter, Saturn, Uranus, and Neptune were formed by different types of rock and frozen materials (water, ammonia, and methane). These materials were once planetesmals, which formed from the rocky, metallic solid materials that were able to survive the collapse of the solar nebula which formed our solar system.

The rings have earned Saturn the nickname of “The jewel of the solar system”. Saturn’s rings were first seen by Galileo in 1610. What the rings truly were remained a mystery until 1655, when Christiaan Huygens discovered they were planetary rings. These rings are made up of dust, rock and ice. The rings accumulate these items from passing comets, impacts on its moons from meteorites, and the planet’s gravitational pull. Although Saturn isn’t the only planet with rings, it is given the most credit. This is because its rings are the largest and most vivid out of the planets. Each ring orbits the planet at a different speed. The rings have simple names. The A,B,C,D,E,F, and G ring. There are more specific names but this is their simple form. The gaps in between them are also named. Each gap and ring range in size, and have different features found in

Most people in their lives have seen a shooting star and exclaimed, “Make a Wish!” However, this so called “shooting star” is actually the clue to how the solar system was created. While this rock object is in space it is called a meteoroid, and then it is called a meteor when it enters a planetary atmosphere. The friction of the meteoroid created by the incoming velocity causes it to heat up quickly, and in result a bright flash of light. As noted above, this is what people see when watching the sky. In addition, meteorites gave the first knowledge about abundances of chemical elements in the solar system in the 1930s through 1950s. Meteorites are the most ancient rocks known to mankind and have helped pave the way in the study of the formation

Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to

It took Matthew Doe two decades to regain his sanity. He had an unhappy marriage to a witch named Silvia who only wanted his money. She would be out late cavorting with friends and lovers while he stayed at work. Work for Matt was at a mental hospital called ‘The Barn’ by locals of a small town that he never visited. Matt was ‘organized’ perhaps to a fault but Silvia was a pig. The remnants of her flings and parties continuously strewn throughout their suite. “Pick up after yourself just a little! Is one shoe or a purse too much to ask?” Matt would bellow at his intoxicated wife. “Shut up you stupid lout!” was usually her dignified, shrieking answer. “Join the army if you want everything to be perfect! Then you could find some

Planets have mass and therefore have an effect on their stars orbit causing it to wobble. The wobble in the case of a pulsar star is seen as the periodic delay in the arrival of the pulses from the pulsar star (Wolszczan 1994). Due to the nature of a Pulsar star we can detect perturbations in its orbit through its pulses but to detect perturbations in other stars orbits, astronomers use a stars radial velocity.

The space debris population consists mostly of explosion fragments, but also includes operating and expended satellites; mission-related objects such as shrouds, clamps, and

Apart from gigantic celestial bodies, it is surprising that microscopic subatomic particles inside matter like electrons are also moving in orbits around the nucleus of the atom. These are all energy particles and are responsible for matter formation and destruction.
