Solar System Boundaries

Heliocentric: Heliocentric is a model of the solar system that represents the sun as in the middle.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

sun than Earth, or 97 Astronomical Units (AU). For comparison, Pluto is 40 AU from the sun.

1. Do the planets of Kepler 11 match the pattern of t2/t3? Support your answer.

At first, we must talk about the whole system, I mean the solar system. The solar system consists of 8 planets and many dwarf planets. Pluto has become a dwarf planet since 2006 this for who will take about 9 planets. The Sun is our store which provides us with energy and heat. Sun can control all planets and comets in a field of its gravity; which covers a great area in space. The Sun moves at a speed of 20 km/s or 12 mile/s towards constellation Lambda pulling all planets with it around our galaxy ''The Milky

This essay took you through the implications of the telescope to our understanding of the universe, the telescope's discoveries, , the Hubble space telescope’s description, and Hubble’s life story. As a wise man once said, “We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe.”- Edwin

The solar system is so big and has been around for such a long time that my sister explained that it began with The Big Bang. The Big Bang theory is very confusing, but I know that it happened about 13.8 billion years ago to create our universe. There are many galaxies in the universe and we are in The Milky Way, I know I first thought of the candy bar, but that is wrong and it is home to our solar system. At the center of the solar system is the sun, the sun is only 4.6 billion years old, and I first thought the Sun was the largest plant in our solar system, but it is not a planet it is a yellow dwarf star. Its radius is 432,168.6 miles, it is way bigger than any of our planets in our solar system. If we were to compare the size of the Earth

6. Space is almost unfathomably huge. Our sun is just one of the 400 billion stars in our galaxy. The observable universe has an estimated 170 billion galaxies. Each of those galaxies has billions of stars, some with as many as a trillion or even 100 trillion. That means there are at least a septillion stars in the observable universe (10,000,000,000,000,000,000,000,000). Can you imagine how many planets are orbiting all those

Our very own solar system consists of the most important star called the Sun, it provides earth with the necessary energy in order to sustain life. There are 8 planets revolving around the sun and they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus,Neptune , and Pluto. However Pluto is no longer considered a planet. But that is still debatable. The Sun is the center o the Solar System, it has a nearly perfect sphere shape of hot plasma that generates a magnetic field. The asteroid belt is a circumstellardisc which is located in the Solar system between the planet of Mars and Jupiter. The solar system is just one of the many galaxies in our universe and there are more galaxies yet to be discovered.

The snow line, also known as the ice line, is a point in our solar system somewhere between Mars and Jupiter which separates the regions for formation of the high-density Terrestrial planets from the low-density Jovian planets. This line refers to the kind of matter that can condense in a particular region depending on the temperature of gas there.

The Solar System that I have chosen to create is a very large solar system. The star is a very gas oriented one that produces light just like our sun does. The density of my star happens to be somewhat light.There are two planets that have been made so that people that can live on. These two plants are the 3rd and 4th planets in my solar system.The first planet that is made for civilization is called planet grengion. It is the size of earth. The second planet is a little bigger than the first planet but it still can have civilization on it. This planet's name is Derigon. In the solar system that I have created there is a gas giant. There are also two rocky planets. There are my 5th and 6th planets that are in my solar system.There is rainbow

For centuries, researchers have been looking for more planets in our solar system, with more public focus on the matter in the past decade after Pluto’s reclassification to “dwarf planet”. At last, astronomers have found a possible expansion to our local solar system, or at least this is what the Science News article “Shadow Planet”, written by astronomer Christopher Crockett, implies. In this article Crockett summarizes the history of the idea of a “Planet X” in our solar system, providing the necessary background to understand the rest of the article, where he discusses evidence that heavily supports the idea of a new planet far in our outer solar system.

Planetary boundaries serve as natural thresholds for which humans cannot cross if they wish to continue living on planet earth. Although conditions are currently in the Holocene, which refer to a stable interglacial period, rapid human exploitation including CO2 emissions and land usage are driving us out (Rockstrom and Klum 2015). If human exploitation continues at such a rapid rate we will be pushed past the threshold and into a period which has never occurred in history. Planetary boundaries are important to understand because scientists cannot fully predict what may happen if we do go past them and they set natural guidelines that must be followed if we wish to preserve the planet. In conclusion, planetary boundaries are a very serious

SC.8.E.5.3: Distinguish the hierarchical relationships between planets and other astronomical bodies relative to solar system, galaxy, and universe, including distance, size, and composition.

How to measure the distance in space? Since the distance is so far we have to use light year as a unit for measurement. Light year is the distance that light travels in a year. Light travels very fast. It travels 297,000 km per second. The sun is very far away from us, but it takes only 8 minutes 17 second for sunlight to reach our earth. The brightest star we can see in the night sky is Sirius, but it is very far away. Its light has to travel 8 years to reach us. The farthest object we can see is 13,200 million light years from the earth! Yet, it is not the farthest,
