Does the planet earth originate from the sun?

Question

do all the planets of our solar system originate from the sun - which means at one time the solar system was just the sun and then bits flew off, cooled down and became planets

Answer 1

No. The sun and the planets all formed from the same cloud of dust and gas at around the same time.

Answer 2

the big bang created dust and the dust clumped together and after billions of years the earth is know  what we know it as.

Answer 3

No;around 4.5 billion years ago,a cloud of dust and gas pulled together by gravity and began rotating.The material at its centre heated up to form the proto-sun.Other circulating matter accreted together to form the planets,which orbit the sun in the same direction and the same plane.So, the sun was created first and the other planets were formed later from the same cloud of dust and gas.

Answer 4

Yes, we all came from the same pool of space debris left over from the big bang.  The sun was ignited because of it's huge mass. Jupiter could also be a star if it were bigger. What isn't big enough to become a star cools down and becomes a planet.

Answer 5

yes... all the planets are originating from our sun only including our earth.

Answer 6

the sun and the planets are leftovers from a supernova. it left a bunch of dust and gas behind that eventually formed into what we have now.

Answer 7

No.  The cloud of materials that formed the solar system originated from materials from many nearby supernovas.  Several generations of stars lived and died before our nebula began to contract.  The sun and the planets formed at the same time by the process of accretion from this nebula.  Small lumps of matter collided with other small lumps to form larger lumps which in turn collided with other lumps and grew...

   Being in the center of the system where most of the mass was located, the proto-sun lump grew the fastest and the biggest. Much larger than any of the more distant lumps. So large that as it contracted the core heated up to millions of degrees and nuclear fusion of hydrogen atoms into helium and the resulting release of vast energies took place.  This energy ionized the matter of the proto-star as it moved toward the surface and eventually the sun was born.    

Away from the proto sun, planetary formation was a bit more chaotic with planetary bodies colliding with each other.  Orbits weren't exactly stable yet and continuous asteroid impact built up the planetary masses.  It took some time before things settled down and the current planets were in their current orbits.  

Answer 8

The origin of the Earth

The age of the Earth was once, and still is, a matter great debate. In 1650 Archbishop Ussher used the Bible to calculate that the Earth was created in 4004BC. Later on in the mid-nineteenth century Charles Darwin believed that the Earth must be extremely old because he recognised that natural selection and evolution required vast amounts of time.

It wasn't until the discovery of radioactivity that scientists began to put a timescale on the history of the Earth. Rocks often contain heavy radioactive elements which decay over long periods of time, the decay is unaffected by the physical and chemical conditions and different elements decay at different rates (These rates are slow and half-lifes of several hundred million years are not uncommon)

Throughout this century the race has been on to discover the oldest rocks in the world. The oldest volcanic rock found so far has been dated at 3.75 billion years old, but this is not the whole story. Meteorites created at the same time as the Earth hit us all the time, radioactive dating shows that they are about 4.55 billion years old.

THE EARLY ATMOSPHERE

The present composition of the atmosphere is: 21% OXYGEN

78% NITROGEN

0.04% CARBON DIOXIDE

~0.9% ARGON

The atmosphere wasn't like this when the Earth was created over 4½ billion years ago.

THE FIRST BILLION YEARS

The Earth's surface was originally molten, as it cooled the volcanoes belched out massive amounts of CARBON DIOXIDE, STEAM, AMMONIA and METHANE. There was NO OXYGEN. The STEAM condensed to form water which then produced shallow seas.

Evidence points to bacteria flourishing  3.8 billion years ago so this means that life got under way about 700 million years after the Earth was created. Such early forms of life existed in the shallow oceans close to thermal vents, these vents were a source of heat and minerals.

THE NEXT BILLION YEARS

These primitive life forms then took the next evolutionary step and started to PHOTOSYNTHESISE (using sunlight to convert carbon dioxide and water to food energy and oxygen). This was an important turning point in Earth history because the carbon dioxide in the atmosphere was being converted to oxygen.

These green plants went on producing oxygen (and removing the CO2).  

Most of the carbon from the carbon dioxide in the air became locked up in sedimentary rocks as carbonates and fossil fuels. Carbon dioxide also dissolved into the oceans.

The ammonia and methane in the atmosphere reacted with the oxygen.  

Nitrogen gas was released, partly from the reaction between ammonia and oxygen, but mainly from living organisms such as denitrifying bacteria. (remember that nitrogen is a very unreactive gas and it has built up slowly).  

THE LAST 2½ BILLION YEARS OR SO

As soon as the oxygen was produced by photosynthesis it was taken out again by reacting with other elements (such as iron).This continued until about 2.1 billion years ago when the concentration of oxygen increased markedly. As oxygen levels built up and then . . . . . .

The ozone layer was formed which started to filter out harmful ultraviolet rays. This allowed the evolution of new living organisms in the shallow seas.
