Planetary Migration

“A bizarre wobble 65 million years ago, perturbing the orbits of Mars, Earth and Mercury, may have caused the demise of the dinosaurs, new models of the Solar System suggest.”

Jupiter is a VERY important planet. Not only does is it the biggest planet in our solar system, but it keeps thousands of minor planets in their orbits. There is a family of minor planets (or asteroids) in the same plane as Jupiter. These are called Trojan asteroids. Scientists have divided these into two groups the “Greeks” and the “Trojans”. The “Greeks” come before Jupiter and the “Trojans” follow Jupiter. These asteroids are as far away from Jupiter as they are from the sun; because of this they stay and will continue to stay in the positions they are in because the gravitational pull from Jupiter and the sun are the same.

Neptune is the eighth planet from the sun. The deep blue color of Neptune comes from its atmosphere. Neptune also has a system of rings. Neptune’s rings are made of ice particles coated with carbon-based materials, giving them a reddish color or shade. Neptune sometimes shows a dark spot known as “the great dark spot”. The 8,000 mile long spot, which resembles Jupiter’s Great Red Spot, is a huge area of storm movement. Unlike Jupiter’s

Such an era came to a staggering end from the grand celestial meteoroid which assaulted life into

Neptune is the eighth and final planet from the sun. Discovered in 1846, it was a mystery to all, being that it is invisible to the naked eye. Neptune formed like a terrestrial planet with a solid core, but then it captured gases like hydrogen and helium when in the nebula of the original and early sun, making this planned a jovian planet. Neptune was discovered using mathematics, unlike all the other planets. The path of Uranus was not traveling like everyone though it should have been, from there on mathematician Urbain Joseph Le Verrier proposed that there was a unknown planet in a position with a mass that was causing Uranus to be so off of the predicted course. His predictions were not taken seriously by French astronomers, so he took

Astronomers have identified plenty of objects that were circulating the sun farther away from Neptune since the year 1992. According to research, there are more than 70,000 of these small objects named as Trans-Neptunians, which had a diameter that was larger than 100 km. Also, these objects extended from Neptune’s orbit from 30 astronomical units (AU) to 50 astronomical units. There is a thick band in which these Trans-Neptunians were restricted in and this ring was named as the Kuiper Belt. One may ponder what is the significance of the Kuiper Belt? Astronomers believe that the objects within the Kuiper Belt may be the ancient remains from the early stages of development of the solar system.

As mentioned earlier, Pluto has a rather unusual orbit. Pluto, while it is the furthest planet from the sun, for twenty years during its two-hundred and forty nine year orbit, it is actually the eighth planet, crossing over Neptune’s orbit. Regardless of the fact that the orbits of the two planets cross, their orbits will not allow for them to ever collide. This is mainly due to Pluto’s orbiting not staying in the elliptic plane. Because of its unusual orbit, Pluto travels above and below Neptune as the cross, avoiding collision. What also allows these two bodies to cross paths and avoid impact is that when Pluto is at one side of the sun, Neptune is at the other. This is a result of Pluto taking three times as long to make one orbit around the sun in comparison to Neptune.

The discovery of the Neptune planet was the result of various hypotheses, generated by different astronomers and mathematicians from 1781 to 1847. The article entitled “Accounting for Anomaly: The Discovery of Neptune” describes how Neptune was mathematically identified, before being directly observed, using the calculations of Urbain Le Verrier. He made the hypothesis that the Newtonian gravitation law could not fully explain the series of irregularities in the path of the Uranus planet. Le Verrier suggested the existence of another planet, after Uranus, that could affect its gravity. In 1845 his hypothesis followed a series of calculations to determine the nature and position of this unknown planet. By this calculations Le Verrier’s understood

It goes to show the constant shifting from place to place in the eyes of a mexican immigrant. This last paragraph is explaining that they come and live in a place for a while but never for long. They are afraid they will be found out and so result to running endlessly. He talks about upon walking through the front door, he saw cardboard boxes and everything was packed up. They didn't have much but the little the did was bundled up and ready for travel. This implies that they are poor and are living a life similar to a hamster in a cage. Constantly running away from the cruelty of the world. This should be an explicit example of the pain and suffering barriers give off. They separate us from exploration, discovery, and the continuation of the

After researching about astronomy and the discovery of Uranus by William Herschel in 1781, I learned a lot about Uranus. I think one of the most shocking things about the discovery of Uranus was that William Herschel wasn’t even a professional astronomer, he was actually a musician. He did have an interest in astronomy on the side which is what led him to discover Uranus. He built many telescopes and he found the planet in one that he had built himself and at first he thought it was a comet. After studying it for many days, alongside many other astronomers, he discovered it wasn’t a comet at all. He and the astronomy community continued to study Uranus and they discovered how different it is from the other planets. I love how Herschel discovered

Before the discovery of Uranus there was thought to only be seven heavenly bodies, the Sun, the moon, and five planets. It was common knowledge at the time that they were the only other objects in the Solar System and there would be no others. It changed in 1781 when William Herschel discovered a new object, which later became known as Uranus. (Teerikorni, 111) This all began in 1773 when Herschel started grinding his own lenses and even mounting a mirror with a five and a half foot focal length. He continued in 1776 with larger telescopes. “In July he added a 20ft, and telescopes of 7, 10 and 20 feet becames his common working instruments for some years to come.” (Bennet, 75-76) All of this tinkering eventually led to the discovery of a new

I decided to do further research on the discovery of the planet Uranus because of my interest in the night sky. It was very interesting to learn about how this planet was discovered. Actually the planet Uranus was seen before it was actually discovered that it was a planet. People thought that it was a star. Uranus is really hard to see with just your eyes so the ancient civilizations probably thought it was a distant star. Later on after the invention of the telescope in the 1600’s it was actually cataloged as a star, star 34 tauri, by John Flamsteed. William Herschel discovered that it was a planet quite on accident. He was very interested in astronomy and was cataloging binary stars when he discovered an odd moving

“Toutatis is not a monolith, but most likely a coalescence of shattered fragments. This bifurcated asteroid is shown to be mainly consisting of a head (small lobe) and a body (large lobe)” (Huang ln 50). This object, that shaped like a peanut, does not revolve around in a fixed axis, but constantly turning the somersault. Toutatis is composed of two connected to other objects, in addition, the influence of the earth and Jupiter's gravity; it is the movement of the unpredictable way form part of the reason. Toutatis' path through the solar system orbit close to the earth; but because of the asteroid's orbit is very chaotic, so for centuries, its accurate operational route and more over how close to the Earth, it has been unable to predict very well. Like some other asteroids, it is said that Toutatis looks like a “rubble pile”, together after an in the gravity of these large gaps between rock fragments that have gravitationally come back together after a crash, but left a lot of gap between

our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique.

On the off chance that the planets moved about in roundabout movement then there more likely than not been a cause to realize their movement, consequently, there must likewise be either an unbounded chain of causation for sublime bodies or a prime mover/first reason for the magnificent bodies.
