Introduction
The Kepler Space Telescope was launched into a heliocentric orbit in early 2009 with an aim to detect earth-sized planets orbiting sun-like stars. The previous projects in this field were able to detect only Jupiter sized planets or larger but nothing as small as the Earth. The Kepler Space Telescope aims to detect planets orbiting their star in or near the habitable zone. The telescope also detects the shape and size of the orbital paths of the exo-planets around their stars. By knowing the properties of different star-planet system in our solar neighborhood, we could group them according to similarities and differences. This enhances our understanding of the universe. The final results from this mission will enlighten us more about how a planetary system forms, how frequently and lot more.
This project aimed at finding probable exo-planets by looking at the river-plots and binned folded light curve for the Kepler Objects of Interest (KOI).

DESCRIPTION OF WHAT WAS DONE AND IN-CLASS LAB
The exo-planet lab aimed at discovering planets orbiting other stars. The method used for this lab was the transit method. When a planet passes in front of it star, there is a dip in the usual visible-light brightness …show more content…

The red in-transit dots were needed to lie lower on the curve as compared to the blue out-of-transit dots for a greater rating. The highest assigned rating for this category was 3 and the lowest being 1 on a scale of 1-5. KOI1784 and KOI3933 were the potentials with a rating of 3. The binned folded light curve for the above mentioned potentials had a perfect U-shape and the red in-transit dots were lower than the blue out-of transit dots. The curve didn’t look noisy at all and hence KOI might be of some

Polaris Skylb Lab Report

These graphs resemble the data chart that was explained above. This way of representing the data also shows visually how Cassiopeia crosses its culmination and starts its decent towards the westward horizon. SKYLAB QUESTIONS 1) Stars change elevation more than others because of their relative position to Polaris the further away the stars are from Polaris the larger their apparent circular motion giving the constellation a larger distance to travel as they travel through the night-sky. The way the Earth travels around the sun also effects this because as the Earth travels around the sun the stars in the background will change and their apparent position to Polaris will be different making some stars have to change altitude more than others. 2) (See attached notebook paper for sketch)

Jupiter And Arcturus Lab Report

Therefore, although rays from each side of the planet are indeed refracted, they end up cancelling each other out, and thus do not twinkle like stars do. In other words, rather than a small pin point of light reaching the atmosphere (as is the case with stars), many light beams that are much wider than stars come from planets, which results in the refraction being averaged out between the

Should Pluto Be Considered A Planet?

1095 Words | 5 Pages

Adler Hoffmann Mrs. Rader 8th Grade Language 1 March 2024 Should Pluto be Considered a Planet? Textbooks, websites, school systems, books, acronyms, and more. What do they all have in common? They all had to change in 2006, when the International Astronomical Union (IAU) deemed Pluto, the ninth planet in our solar system, as a dwarf planet instead. At that time, this was a controversial decision because a lot of the general public did not want to have to remove Pluto from anything that mentioned the former nine planets because of the inconvenience of changing these things.

Rogue Planets

224 Words | 1 Pages

There have been many sightings of rogue planets throughout the universe. However, in the year of 2006 it was publicized that one of our most important evidence on the existence of rogue planets. With this evidence, it was recorded, that two planets were orbiting each other without a star. This evidence comes from the European Southern Observatory. Astronomers have predicted based on the following quote, “There could be over 100,000 times more rogue planets in the Milky Way than stars.”

Argumentative Essay On Trappist-1 And Life On Mars

1852 Words | 8 Pages

Trappist-1 is an alien solar system 40 light years from Earth. On the first discovery, scientist found 3 exoplanets that there is a possibility to habitat life. Until now, on February 22, 2017, NASA announced more information on Trappist-1. As stated on NASA’s website, “NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.”

Compare And Contrast Jovian And Terrestrial Planets

444 Words | 2 Pages

Final Exam Planets and moons in our solar system have many differences, such as geologic activity, composition, interior structure, magnetic field, and atmospheres. To start off, there are two different groups of planets in our solar system, terrestrial and jovian planets. The terrestrial planets are Mercury, Venus, Earth and Mars. Terrestrial planets are mostly composed of silicate rocks or metals. The terrestrial planets are the planets closest to the sun.

Search For Exoplanets: A Discussion With Professor Sara Seager

967 Words | 4 Pages

This became one of the few major discoveries in recent years in the field of astronomy. Planets are usually small compared to the star. So, it’s hard to notice the light emitted from a planet when it orbits a star as the light of the star is much larger in size and brighter. Scientists solved this problem by developing two techniques for detecting exoplanets. They are namely, Transit method and Radio Velocity method.

Kepler-452b Research Paper

For many years, it has been believed and scientifically proven that only the planet Earth can sustain life. And without it, we’ll no longer have a place to call home. However, with the Earth’s drastic condition - climate change, greenhouse gases, depletion of the ozone layer, and etc.- the astronomers have been searching for a planet that can save us from the ultimate fate of the Earth- and to also prove that we are not alone. Thus, after long years of research, we have found Kepler-452b. Here is a gist of what has been discovered about Kepler-452b:
