Nobody is known to be credited for the discovery of Mercury, though Timocharis made the first recorded observation of Mercury in 265 BC and does not have an actual discovery date. Mercury also has many notable features that most likely caught Galileo's eye, like it’s similarity to our Earthen moon. Mercury has a variety of craters, ridges and ranged terrain. Mercury can be said as one of the most interesting planets in our solar
A black hole is nothing but empty space that has a gravitational force that nothing can get past it, not even light. It is almost like a massive, vigorous vacuum making it the second to largest black hole astronomers have ever seen. Two million years ago, the black hole was 100 times more powerful than it is today. Scientist are confused why the black hole is weakening because it's suppose to be the opposite. Sagittarius A is about 26,000 light years away from Earth and it is 100 more massive than the
The moon has orbited the earth for over 4 billion years. Many scientists hold different opinions on how the moon was really formed. There are three main thoughts on how the moon was formed, these being:the giant impact theory, the co-formation theory and the capture theory. But the question still remains, how was the moon created? The giant impact theory, Space.com thinks that the giant impact theory is probably the most valid of the three,this theory holds the idea that the as earth orbited the sun in its early days it collided with many other smaller objects (asteroids) that were travelling through space at the time, and absorbed them into its growing mass.
Speed relative to CMB rest frame is 552 km/s. The Milky Way is the second largest galaxy in the local group.Andromeda Galaxy is bigger than the Milky Way. Mass of the Andromeda Galaxy is 7×1011 solar masses (Mo). The Milky Way's steller disk approximately 100,000 light years in diameter and 1000 light years thick. Mass of the Milky Way is 5.8×1011 solar masses (Mo).
It is also one of the farthest planets from our solar system, which causes it to take 4 hours for the sunlight to reach Neptune. Surprisingly, the sunlight we have here on Earth is 900 times brighter on Neptune! Since, Neptune is the windiest planet in our solar system it contains supersonic winds, winds that are 1.5 times faster than the speed of sound. The planet is at least -300 fahrenheit and the hottest it can get is 18 degrees fahrenheit. Neptune has a radius of 15,299.4 miles, it is also four times
Contents Task 1 2 Part A 2 Part B 2 Task 2 4 Part A 4 Part B 4 Task 3 5 Part A 5 Part B 5 Task 1 Part A The Earth is orbited by 2,271 satellites, 10,000 rocks and debris and over 500,000 pieces of junk and smaller debris. But what forces are causing this to occur? Eccentricity is a measurement of how much the conic section deviates from being circular. This means that it is a measurement of how much the orbit (in this case) deviates from the 0 or the center. When a satellite orbits the Earth in moves through an atmosphere depending on the satellite, when this occurs it can begin to venture inwards or outwards of the orbit due to Earth`s seasons and direction change creating a fluctuation in the amount eccentricity the
Discovered in 1781, Uranus is the third largest planet in the solar system. Even though it is bright blue, it is still nearly impossible to spot with the naked eye because it is the seventh planet from the sun. The blue color is due to the composition, which is 83% hydrogen, 15% helium, and 2% methane. The methane absorbs red light, which is why we see the planet as a bluish-green color. The clouds of Uranus are similar to the
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. Kepler-452b orbits its star every 385 days. The planet's star is about 1,400 light-years away in the constellation Cygnus. It is a G2-type star like our
In this great, wide universe, that was theorized by many scientists to be formed by a huge explosion set off by a giant ball of energy (better known as the “Big-Bang Theory”), there is a galaxy called the Milky Way. It is called as such because of the galaxy’s rather “milky” appearance. And in this galaxy’s very edge, there is a group of planets that is being pulled together by a single, bright, yellow star called the “Sun”. This group of planets, along with the Sun itself, are called the “Solar System”. In the Solar System, there are nine planets, which are then again grouped into two groups; the terrestrial planets and the Jovian planets.
Time after time, science and technology have proven that we live on a spherical planet. Now that we have access to space, the easiest way to prove the Earth is a sphere is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere. The horizon is the surface that one is observing from is not an infinite plane.
Pluto, a planet that is only known to the average huan as the reject planet (once the ninth planet of our solar system,but now catorgized as a dwarf planet) and no thing else. So because of this lack of knowlegede scientist at NASA made a spacecraft named New Horizon to find anymore information on Pluto via flyby scan. After 9 and a half years hardship the spacecraft reached its destination. When the spacecraft sent information to the scientist on the dwarf planet scientist were dumbfounded on the output data. New discoveries were found on the once ninth planet and some don 't know what to do.
