Jun 06, 2016 A RESPECTED astronomer sensationally suggested NASA has been covering up the existence of a second sun in our solar system and the fabled Nibiru planet, during a live broadcast. By Jon Austin. . Based on Second Sun simulation software, historical weather data, existing 1000W light rigs available in the stadium and a target of 12 DLI per day - the actual savings will vary based on geographical location, orientation, height and local weather conditions but 500.000 kWh is a conservative estimation applicable for most stadiums across Europe with existing artificial light rigs. The hypothesized second sun, in order to trap this excess material, would require a mass comparable to our own Sun. So, basically a twin. The two stars would would have been roughly 1,000 AU apart.

The Sun, at the center of our Solar System, is at the beginning of this scale model of the Solar System. In this model, the Sun is represented as a ball 4 inches in diameter. This makes the scale of our model 1 inch = 180,000 miles. Each step that you take (28 inches) is then 5.0 million miles.

The Sun, at the center of our Solar System, is at the beginning of this scale model of the Solar System. In this model, the Sun is represented as a ball 4 inches in diameter. This makes the scale of our model 1 inch = 180,000 miles. Each step that you take (28 inches) is then 5.0 million miles.
Our Sun is a huge, massive, spherically shaped object, containing about 99.8% of all the matter in our Solar System. (The planet Jupiter contains most of the remaining material.) The sun has a mass of 1.9891x1030 kg = 4.384x1030 lb = 2.192x1027 tons, or a mass 333,000 times that of the Earth. The radius of the Sun is 696,265,000 meters = 696,265 km = 432,639 mi or a radius 109 times that of the Earth. The volume of the Sun is so huge that it could hold over 1 million Earths.
The Sun is a typical star, and is also the star that is nearest to the Earth. It is composed of a mixture of 73% hydrogen, 25% helium, and 2% other elements by weight. The nuclear fusion reactions that produce the sun's energy are converting hydrogen into helium, changing the relative amount of these two elements present in the Sun. In each nuclear conversion 4 hydrogen atoms are combined to produce a helium atom. This reaction occurs throughout the Sun and by this process our Sun converts 600 million tons of hydrogen into 596 million tons of helium every second. The missing 4 million tons of matter are converted to energy, according to Einstein's equation E=mc2. This amount of energy is so large that the Sun gives off 40,000 watts of light from every square inch of its surface. (Compare this to the 60 and 100 watt light bulbs we use in our homes.) As far as we know, the Sun has been giving off this energy steadily for the last four and one half billion years, and will continue to do so for several billion years more. Only half a billionth of this energy reaches the Earth. The rest is radiated out into space. To Planet Walk Home Page | To Prof. Dorneman's Home Page | To MCCC Home Page |

Planet-Like Body Discovered at Fringes of Our Solar System
What's bigger than an asteroid, smaller than a planet, red all over and far, far away? The answer -- a mysterious planet-like body orbiting our Sun -- has been discovered by NASA-funded researchers led by an astronomer at the California Institute of Technology, Pasadena, Calif. Image above: These three panels show the first detection of the faint distant object dubbed 'Sedna.' Imaged on November 14th from 6:32 to 9:38 Universal Time, Sedna was identified by the slight shift in position noted in these three pictures taken at different times. Image courtesy: NASA/Caltech.
The object is three times farther away from Earth than Pluto, making it the most distant known in the solar system.
'The Sun appears so small from that distance that you could completely block it out with the head of a pin,' said Dr. Mike Brown, Caltech associate professor of planetary astronomy and leader of the research team. The object, unofficially named 'Sedna,' is 13 billion kilometers (8 billion miles) away from Earth.
This is likely the first detection of the long-hypothesized 'Oort cloud,' a faraway repository of small icy bodies that supplies the comets that streak by Earth.

In the distance is a hypothetical small moon, which scientists believe may be orbiting this distant body. Image courtesy: NASA/JPL-Caltech.
Other notable features of Sedna include its size and reddish color; it is the second reddest object in the solar system, after Mars. At an estimated size of three-fourths the size of Pluto, it is likely the largest object found in the solar system since Pluto was discovered in 1930.
Brown, along with Drs. Chad Trujillo of the Gemini Observatory in Hawaii and David Rabinowitz of Yale University, New Haven, Conn., found the 'planetoid' on November 14, 2003, using the 48-inch Samuel Oschin Telescope at Caltech's Palomar Observatory near San Diego. Within days, the object was observed by telescopes in Chile, Spain, Arizona and Hawaii, and soon after, NASA's new Spitzer Space Telescope looked for it.
Sedna lies extremely far from the Sun, in the coldest known region of our solar system, where the temperature never rises above minus 240 degrees Celsius (minus 400 Fahrenheit).
The planetoid is usually even colder, because it approaches the Sun this closely only briefly during its 10,500 year orbit around the Sun. At its most distant, 'Sedna' is 130 billion kilometers (84 billion miles) from the Sun. That is 900 times Earth's distance from the Sun.
Scientists used the fact that even the Spitzer telescope was unable to detect the heat of the extremely distant, cold object to determine that it must be no more than 1,700 kilometers (about 1,000 miles) in diameter, smaller than Pluto. By combining all available data, Brown estimates the size at about halfway between that of Pluto and Quaoar, the planetoid discovered by the same team in 2002. Until 'Sedna' was detected, Quaoar was the largest known body beyond Pluto.

The extremely elliptical orbit of Sedna is unlike anything previously seen by astronomers; however, it resembles that of objects predicted to lie in the hypothetical Oort cloud. The cloud is thought to explain the existence of certain comets. It is believed to surround the Sun and extend outward halfway to the star closest to the Sun. But Sedna is 10 times closer than the predicted distance of the Oort cloud. Brown says this 'inner Oort cloud' may have been formed by gravity from a rogue star near the Sun in the solar system's early days.

Rabinowitz says there is indirect evidence that 'Sedna' may have a moon. The researchers hope to check this possibility with NASA's Hubble Space Telescope.

'Sedna' will become closer and brighter over the next 72 years before it begins its 10,500-year trip to the far reaches of the solar system and back again. 'The last time 'Sedna' was this close to the Sun, Earth was just coming out of the last ice age; the next time it comes back, the world might again be a completely different place,' said Brown.
