Kepler-452b Observation

Kepler -452b is believed to be a rocky planet and is said to be made up of a mix of silicon, carbon, magnesium and iron (elements found throughout Earth and other rocky planets) with active volcanoes, can keep water and oceans and an atmosphere that can hold gases. Simulations can prove that Kepler -452b is habitable as CO2 concentrations in its atmosphere are comparable and slightly lower than in Earth present day. With the help of models and research, we can assume that the planet is very likely to have a dense atmosphere due to it’s size and is too likely to carry liquid water. In addition, the sky is most probably blue similar that of to earth and if there were to be molecular oxygen in the atmosphere - produced by photosynthesis -, it could suggest native plant growth and can also host and allow Earth’s plants to photosynthesize due to the similarity of suns. Therefore, not only can learn to grow the local flora, but bring Earths to sustain ad create a greenhouse and/or gardens.

A red dwarf star’s HZ, for example, would be much closer to the star itself compared with that of our sun. It is also important to determine the planet’s size and mass, which is imperative in deciding whether it can sustain an atmosphere. Maintaining an atmosphere is essential for life to exist and small a planet with a small gravitational force at its surface may not be capable of retaining one. The Kepler transit data can only measure planet masses, diameters, orbital periods, and parent star types and although this information is useful for determining habitable zones, further data is required to determine true habitability. The latter can be done by studying the composition of the exoplanet’s atmosphere.

As technology improves it is even more likely that we will discover more about our solar system. A great current example of this is the claim of ‘Planet X’. Researchers say that there is possibly another planet in our solar system that orbits beyond Neptune but is large in size. Two scientists recently announced evidence that a body nearly the size of Neptune that orbits the sun every 15,000 years. Since it has never been seen, because it only orbits every 15,000 years, scientists and researchers cannot make a factual claim on the body even though there is strong evidence of its

The exoplanet known as Kepler-453b is what is known as a circumbinary planet. A circumbinary planet is a planet that orbits two stars, and Kepler-453b is the tenth such planet discovered so far. It is a timely discovery not only because it was discovered at around the same time that news broke out of the world’s superpowers looking to make Star Wars a reality by waging war in space, but also because the real-life Tatooine was discovered by chance in a classic case of being in the right place at the right time.

This implies that the Kepler 11 planetary system is very much like our solar system. The distance (m) of Kepler-11b

However, Earth does not orbit around an M dwarf, as our sun is much larger and burns brighter. David Charbonneau, a lead astronomer for MEarth at Harvard, says that “This is the first time we’ve found a rocky planet that gives us the opportunity to look for oxygen. This is the one we have really been hunting for.” Ironic, because the organization almost missed the planet’s existence; not surprising, considering how dull the star LH 1140 burns. LH 1140 b’s transit was tentatively detected by a single MEarth telescope in a Chilean observatory. To confirm that the planet was actually there, MEarth received help from the European Southern Observatory, also based in Chile, which uses a HARPS program to detect planets, as opposed to transits. The program detects the forces of gravity that a planet exerts upon its star, and traces the movements and interference. Doing this allows the astronomers to estimate planet mass, as well as distance from the star. The head of the HARPS program, Xavier Bonfils, says that the transit event detected by MEarth was very low signal and high noise.

Lee Billings' article in Scientific American, "Do 3 Habitable Super-Earths Really Orbit a Nearby Star?", reports on the possible discovery of additional planets by multiple sources. The planets in question orbit the Gliese 667 C star, and were detected by a team of astronomers composed of Gulliem Anglada-Escuede of Germany's Gottingen and by Hertfordshire's Mikko Tuomi, as well as by Philip Gregory in Canada. Both of these respective researchers utilized data from the HARPS spectrograph to study 7 planets orbiting the star, three of which may be able to sustain life. The researchers used HARPS data with statistical processes to discern the fact that the planets produced a "wobble" (Billings) on the star, which indicated that they could be actual planets.

In the essay “Finding Another Earth,” author Pat Brennan, PlanetQuest reports the new finding planet same as our home planet. The author says a habitable zone shows the band of congenial temperatures for planetary orbits. It can say which planet has a habitable zone and could have water on its surface. The author explains that planets in habitable zones or not depend on many factors like if it’s very near from its star and it been to hat and can’t be a habitable zone. Kepler-452b is the most similar to the Earth-sun system found yet. Although Kepler-452b is the most similar to the Earth, other planets are nearly similar to the Earth too. Before Kepler-452b was found, the planet Kepler-186f held the “most similar”. Kepler-186f has a 130 days

Recently we have discovered an oddly shaped object that orbits the sun. For all intents and purposes it shall be called “Object X” or “X” for short. We have observed it passing through an asteroid field ten times. It has a moon that orbits 19,570 kilometers from

The centuries old quest maybe as old as NASA has been started for other words like our earth has been rejuvenated by the intense surrounding the discovery of hundreds of planets. The kepler mission, which is one of NASA’s best discovery missions it is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near a habitable zone.

One of the first thing that he came up with was he made three laws, later known to be called Kepler’s laws. The first law he came up with is that planets rotate in elliptical paths around the sun. Which leads to his second finding and then later became known as his second law, he figured out that planets rotations are faster as they get more near the sun, then slower as they get further away from the sun. His third and final law dealt with the distance between the planet and the sun and how long it completed an orbit around the sun. Kepler used basic and simple mathematics to figure out how planets move, which proves him to be a very intelligent man at his time and in history. Kepler’s discoveries as well as many other astronomers put him and

The Kepler Telescope in its quest to find other planets like Earth made a breakthrough discovery on July 2015. NASA scientists announced the discovery of Kepler-452b. An exoplanet, a planet outside our solar system that orbits a far off star, named after the star it orbits which is called Kepler-452. Kepler-425b has numerous similarities with Earth that is why scientists are now eager to determine if it is hosted or has hosted life. It orbits a single star and is located at the so called habitable zone, a sweet spot where a planet could potentially harbor water because it receives the right amount of sunlight, much like the Earth (orwig & kiersz, 2015). Dubbed as the “bigger, older cousin of Earth” (NASA, 2015), the announcement has been met with a lot of excitement. But with excitement, comes ambiguity.

Another drawback is that the amount of false positive candidates is higher than many other methods and it’s thought that, in some cases, as many as 35% of detected planets from Kepler are false. This means that in some cases follow up investigation is required before a planet can be confirmed. A common source of false positives is caused by fluctuations in the star’s brightness which are not caused due to a transiting planet but are often hard to differentiate and so they can cause false negatives
