Exoplanet Surface Conditions

Uranus is the only giant planet whose equator is nearly at right angles to its orbit and has 5 large moons and 22 smaller moons. It is, also, the only planet in our solar system to spin on its side. Uranus

First of all, Inner planets are different from Outer planets in many ways. The surface of Inner planets compared to Outer planets are rocky, Inner planets are denser, all the Inner planets are in the asteroid belt. “The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”-Carl Sagan.There is nothing more than what there is. The surface of the Inner planets is very different from those of the Outer planets because, Earth compared to Uranus is completely different due to Uranus being mostly made out of gas. The Inner planets are also much denser than Outer planets. For example, Venus ' average density is 5.24g/cm3 as opposed to Neptune which is 1.33g/cm3. Lastly,

What do you think we would do if someone from anther planet landed in the U.S and claimed it as his territory because he had discovered it? How would you feel about this?

I) Explain how we can deduce each of the properties and summarize the range of each

From the figure above, it can be seen that Gliese 581 G has drawn much notice because of how similar its features are in comparison to our planet. Theoretically, the planet can sustain liquid water on its surface and maintain life comparable to that on Earth based on the planet’s atmospheric conditions. The planet is predicted to have temperatures between −37 to −11 °C, which allows the existence of liquid water. Figure 3 also illustrates that Gliese 581 G is reflected as a Super Earth because it has a mass of about 2.2 times the mass of Earth. It can be seen that the planet is believed to have similar proportions of land and water. It is nearest in mass to Earth identified in a habitable zone. These characteristics have made Gliese 581 G one

much a star wobbles or goes around the centre of gravity of the exoplanet and star, the violent wobbles must conclude that 51 Pegasi b is a Jupiter sized exoplanet. Hd209458 b is also a Jupiter sized exoplanet, which may have been determined using the calculation or the wobble method, having similar affects to its host stars light spectrum as 51 Pegasi b has on its host star. Astronomers are unsure whether the exoplanet named Kepler 22b is a larger Earth or more of a mini Neptune, as it is boarder line between a rocky planet and a gas dwarf.

This experiment was conducted to study and investigate if extraterrestrial life exists upon the exoplanet TRES 2. It was hypnotized that TRES 2 did not sustain the qualifications to support extraterrestrial existence. The results from this testing conclude the hypothesis was correct, with research as an addition from the luminosity testing it has been knowledge that TRES 2 reflects less than 1% of light making it one of the darkest exoplanets currently discovered. Light is a crucial element in the building blocks of life, it is the most important factor that influence the way life evolved on Earth. From photosynthesis, which is responsible for making producing nutrients in plantae’s and meeting our energy requirements. Furthermore TRES 2 orbits

When Pluto is close to the sun in its orbit, the warmth from the sun heats up the frozen ices of nitrogen, methane and carbon monoxide on Pluto’s surface. The ices vaporize and a temporary atmosphere forms. When Pluto gets far away from the sun, the atmosphere freezes and falls back on Pluto’s surface. Pluto is too cold for liquid water. Any water on Pluto is ice. Pluto is so cold that even gases such as carbon monoxide, methane, and nitrogen exist as frozen solids. There is no liquid on Pluto’s surface, it is way too cold for that. There is a small possibility that beneath Pluto’s icy surface, there is a small liquid ocean where things are somewhat warmer.

The new planet is known as HD 219134b and it followed NASA's discovery of the planet Kepler-452b, discovered by the Kepler telescope. The Kepler-452b apparently resembles Earth much more than the HD 219134b exoplanet. It maintains a 385 orbit and its host star is only 20 percent brighter than the Earth's sun. However, HD 219134b is much closer to Earth than the Kepler-452b, and for that reason, scientists have high expectations from it.

This brings us to Proxima B’s amazing features, starting with its size. Most exoplanets we have found in the past have been very large and are comparable to the large gas giants in our own solar system. But Proxima B is much smaller and is only slightly more massive than Earth. It is also moving very quickly around its host star, completing a full orbit in around 11 days - much shorter than Earth’s 365-day orbit.

From the 14 Grand Challenges listed by the NAE, the most important one, I believe, is shifting to a focus on engineering the tools of scientific discovery. It is true that while engineers create the world, scientists discover the one we have now. Why separate the two? By combining the Sciences and Engineering, we are set to discover so much more than we ever thought ourselves capable of. This has already been proven with virtually every scientific discovery that has been made true through the form of some complex apparatus, but this is further proven through this year’s TRAPPIST telescope discovery of the seven exoplanets found orbiting around a single star. While this discovery was a huge achievement for scientists, this would not have been

Spitzer map reveals extreme temperature fluctuations from either side of a planet which suggests Lava flow. Observations from the Spitzer Telescope has led to the first temperature map of a super earth planet. This super earth, is rocky and about twice as big as our earth. These finding say that the planet has hot nights and even hotter days. This finding concludes that the heat is not efficiently transferred on the planet. Even further this shows that there could be an atmosphere that would exist only on the day side of the planet, or by lava flows. The super-earth 55 is Cancri e is about 40 light years away. It orbit close to its star, going around it in only 18 hours.

An exoplanet is a planet that orbits a star that is out with our solar system. A large number of exoplanets have been discovered so far, however it is exoplanets that are within the star’s habitable zone that are the most sought after. An exoplanet is considered to be within the habitable zone if it is at an orbital distance from the star it orbits that allows it to be at a surface temperature that can support water in its liquid state. If the exoplanet is too close to the star any water will boil and evaporate, while if it is too far away the planet will be

These planets also known as, Exoplanet , are found outside our solar system and orbit around its host star; its said to be the most common stars in the Universe. The reason for this is because they exist with the habitable zones of their stars, where liquid water could pool on the surface of the planet and potentially support life. Many astrobiologists believe that in order for life to arise and survive, it must be found on a planet or moon within the habitable zone of a star. The size of the star is important as well; Stars that are much larger than the Sun have such short lifetimes, that it is unlikely that there would be enough time for any kind of life, particularly complex life, to develop. Planets in the habitable zone of small stars

The first exoplanet found, Peg 51 b, challenged the then present theory of giant planet formation. Models of giant planet formation stated that Jupiter-like planets form at distances of 4-5 AU, AU being the distance from
