Mass of the Milky Way is 5.8×1011 solar masses (Mo). Sun's distance to Galactic center is 26,000 light years. Sun's Galactic rotation period is 220 million years. Escape velocity at Sun's position is 550 km/s.This step, stars will be investigated.The globular clusters in the Milky Way have proven through this century to be irreplaceable objects in an amazingly wide range of astrophysical studies. (Harris, 1996).
This sun is 432,288 miles across and the galaxy is supposedly 6,213,711,922 miles wide. It takes 250,000,000 light years for the sun to orbit the galaxy. There are approximately 100 billion different solar systems in the Milky Way. Our dolor system is 25,000 light years away from the center of our galaxy. Our galaxy is so big we have only gone 19.5 kilometers from home.
However, the question is not if Earth will become inhabitable, it’s when it will become inhabitable. Humans will eventually have to venture out into space, and we need to do it now instead of waiting until it is too late. Plus, some of the discoveries made in space can help save our planet, like a discovery of a plentiful source of ununpentium. There is also the fear of finding extra terrestrial life, and bringing it back to earth. Not necessarily alien like creatures that will invade earth, but like bacteria or viruses that can be detrimental to human life.
Here is a gist of what has been discovered about Kepler-452b: Kepler-425b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable zone is a region around a star where temperatures are right for water- an essential ingredient for life, as we know it- to pool on the surface. However, scientists do not know if Kepler-452b can support life or not. What is known about the planet is that it is about 60 percent larger than Earth, placing it in a class of planets dubbed "super-Earths." While its mass and composition are not yet determined, previous research suggests that planets the size of Kepler-452b have a better than even chance of being rocky.
Starting off, why was Mercury named Mercury? The Romans only knew of several objects in the sky at this time, the Sun, the Moon, and the five brightest planets. Mercury was named after the Roman messenger god, as it traveled the fastest in the sky. As said from a page created by Wikipedia on the planet Mercury. Mercury is positioned as the closest planet in our solar system to our
A volcano could have erupted which would have caused the same effect. If humans traveled to Mars, this would mean that the human race would not die out completely. Many humans in certain countries are constantly in danger because of the many wars in the world and terrorist attacks. There would be no wars on Mars, or terrorism because military weapons and terrorists would probably not be sent to Mars. Humans would be safer because of
On the night of Wednesday, November 11, I went to the RLM. At 7:25 I observed Uranus at approximately 40 degrees in the east southeastern sky. It only appeared as a small whitish dot against a vast black background. I found it by looking directly into the lens where the astronomers had pointed the telescope in the sky. Discovered in 1781, Uranus is the third largest planet in the solar system.
We can transform Mars. At the first state building up the atmosphere, it took 90 years and cost 500 billion USD and continues to the last state Mars colonization, it will use 480 years and cost almost 4 trillion USD dollar. Closing: Signal: Well, this brings me to the end of my presentation. (Pause*3) Summary (What): Let me now summarize what I talked about the cause and effect of moving to Mars. Earth and Mars as different as they are alike and even if Mars is devoid of past or present life, however, there 's still much excitement on the horizon.
As I have seen on the news I know that rovers are being sent to mars to study and examine the climate. I also know that the earth is going through massive climate changes that could devastate the human race in the far future. Because it is far in the future you may think that we have all the time in the world and yes that is true but complications will come up and maybe set us back. If we spend just a small amount of our total budget we may have a backup plan that will always be there to save us. I know it may not be clear now but space research is very important and I truly believe that we need
In other words ellipses can be round or elongated; the degree of stretch is known as eccentricity. Eccentricity is defined as the ratioc/2a. C defined as the distance between the two focuses of the ellipse and a is the semi-major axis. In fact, a circle is an ellipse with an eccentricity of zero. Kepler`s second law is the speed of the planets along their elliptical orbits is such that they sweep out equal areas in equal periods of time.
