Big bang: how the universe was created what created all the planets, stars and galaxies bbc future presents a four-minute animated guide to one of the greatest questions we’ve tried to solve. The size of the star, its luminosity, its dark spots, the way the planet revolves around the star (eg, tidal lock), the atmospheric components of the planet, the planet’s rotation and tilt, the size and distance of other planets orbiting around the same star (which could stabilize the habitable planet’s orbit and shield it from asteroids. The solar system appears to have a new ninth planet today, two scientists announced evidence that a body nearly the size of neptune—but as yet unseen—orbits the sun every 15,000 years. Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star the planets nearest to the star tend to be rockier because the star’s wind blows away their gases and because they are made of heavier materials attracted by the star’s gravity. The giant-impact hypothesis, sometimes called the big splash, or the theia impact suggests that the moon formed out of the debris left over from a collision between earth and an astronomical body the size of mars, approximately 45 billion years ago, in the hadean eon about 20 to 100 million years after the solar system coalesced.
Planets grow from the accumulation of smaller, asteroid-sized chunks of rock and metal stars, and possibly also brown dwarfs, form from the collapse of a gas cloud. Small solid planets in the habitable zone are automatically standouts, but matthews singled out five other exoplanets that have expanded our perspective on how planets form and evolve. According to the big bang theory, the temperatures in the early universe were so high that fusion reactions could take place this resulted in the formation of light elements: hydrogen, deuterium, helium (two isotopes), lithium and trace amounts of beryllium. Finally some of these objects became big enough to be spheres—these spheres became planets and dwarf planets rocky planets, like earth, formed near the sun, because icy and gaseous material couldn’t survive close to all that heat.
Bthe big bang (aka “singularity”) was not an explosion, but an expansion of space that continues today cthe first galaxies and stars formed less than a 1/2 billion years after the big bang this image on the left shows how the universe is expanding over time. List of all 315 science video guides uploaded your home for science labs, demonstrations, lesson plans, activities, worksheets, notes, regents review material, educational related information & more. The solar system was formed from a cloud of gas and the wreckage of a supernova explosion artist's impression: nasa it all started with a tremendous bang somewhere in our galaxy a star exploded. In a new twist on the giant impact theory, a new idea posits that the moon might have formed from the vaporized remains of earth after an epic collision with another planet-sized body.
With the exception of the sun, jupiter is the most dominant object in the solar system because of its size and the fact that it was the first of the gas-giant planets to form, it has profoundly influenced the formation and evolution of all the other planets. The big movers and shakers on earth, including plate tectonics, arise from the atomic structure and other properties of earth materials, so scientists want to know more about these properties. The more new planets we find, the less we seem to know about how planetary systems are born, according to a leading planet hunter with the tally of confirmed planets orbiting other stars now more. And when did the first planets form image credit: timotheos samartzidis hip 11952 is located in the direction of the constellation cetus the whale at a distance of about 375 light-years from earth.
The large moons of the gas giant planets (jupiter, saturn, uranus, and neptune) formed in a similar fashion to the planets the small moons of the gas giants, as well as the moons of mars and pluto are probably leftover debris from formation of the planets that were captured by their respective planets’ gravity. How were planets made do planets grow why are the planets round like a sphere question date: 2007-06-07: answer 1: 1 according to the best model we have, the planets in our solar system formed from gas and dust surrounding the sun every object exerts force on other objects through gravity. The planets were formed from the same big cloud of gas and dust that formed the sun that cloud, as it collapsed and started to form the sun, spun faster and faster as it got smaller that is the way spin works — something that scientists call conservation of angular momentum a familiar example is an ice skater.
At the time the drake equation was created, the only planets that were known were those of our own solar system since that time approximately 200 extrasolar planets have been discovered when the drake equation was created, it was thought that planets would only be found in single star systems. Astronomy is more than simply a mapping of stars and planets into outlines of gods and magical creatures it is the scientific study of the contents of entire universe – stars, planets, comets , asteroids , galaxies, and space and time – as well as its history. The planets in our solar system are believed to have formed from the same spinning disc of dust that formed the sun this disc, called the solar nebula, was composed mainly of hydrogen and helium, but also had other elements in smaller proportions the nebula had a certain amount of angular momentum.

The planets in our solar system didn’t appear out of nowhere neither did the sun they were all part of a big cloud of gas and dust gravity collected lots of material in the center to create the sun. The solar system’s big bang that’s when the planets coalesced and water and other compounds essential to life were delivered to the inner planets “if we don’t understand the [earliest] years of the solar system, then we don’t really understand how the planets formed, and where we came from,” says bill hartmann of the. In order to understand how the universe has changed from its initial simple state following the big bang (only cooling elementary particles like protons and electrons) into the magnificent universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed.
In the kepler-20 planetary system there are five planets, he says, three are saturn-sized planets and two are terrestrial-sized, with the order being big–small–big–small–big. Professor stephen hawking explains how the earth and solar system were formed into the universe with stephen hawking - the story of everything. In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean the heat had been generated by the repeated high speed collisions.
