• The sun is the only star in the solar system. Also it’s a medium size star. The sun is hot because its atoms are constantly exploding with in it. Fuel is always burning with in it. The sun is by far the biggest mass in the solar system. During a solar eclipse the main part of the sun is blocked off and only the corona is visible.
Mars is the fourth planet in the solar system. The planet named after Mars, the Roman god of war. Its Also called the Red Planet because of its reddish appearance. It has a thin atmosphere. It has water but only deep into the planet. It has numerous volcanoes.
Jupiter is the largest planet in oursolar system. Its mainly comprised ofgases. So you would find solid groundthere. One notable landmark ofJupiter is the red spot, which is ahurricane that has been going to tensof thousands of years
NEPTUNE known as the blue planet is themost water filled planet in the solar system itsnames after the Greek god Neptune king ofthe sea. It also is a gas giant and is thefarthest planet from the sun.
Difference between a Planet and Star Stars are always much bigger than planets Stars, grow big enough to spark nuclear fusion and planets don’t. Consequently, planets do not shine with their own light, but reflect the light of a local star, and are cooler than stars. Planets are less massive and therefore less dense than stars. stars are made of mostly hydrogen, which they push together to form helium. this is then pushed together to form other elements which are blown into space. a star emits light produced by a nuclear reaction in its core, whereas a planet only shines by reflected light.
In cosmogony,the nebulartheory is themost widelyaccepted modelexplainingthe formation andevolution of theSolar System. Itwas firstproposed in 1734by EmanuelSwedenborg.Originally applied onlyto our own SolarSystem, thismethod ofplanetary systemformation is nowthought to be atwork throughoutthe universe.
The evidence supporting the nebula theory of Solar System formation1. All the planets orbit the Sun in the same direction. Most of their moons also orbit in that direction, and the planets (and the Sun) rotate in the same direction. This would be expected if they all formed from a disk of debris around the proto-Sun.2.
2. The planets also havethe right characteristics tohave formed from a disk ofmainly hydrogen around ayoung, hot Sun. Those pplanets near the Sun havevery little hydrogen in themas the disk would havebeen too hot for it tocondense when theyformed. Planets further outare mostly hydrogen,(since that was what wasmostly in the disk), and aremuch more massivebecause there was somuch more material theycould be made from.
Difference between a planet and starA star contains much more mass than a planet, enough that gravitational forces have compressed thematter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out.. Also, their content is different. stars are made of mostly hydrogen, which they push together to formhelium. this is then pushed together to form other elements which are blown into space. (although onestar nicknamed lucy has got alot of carbon in its core, which because of the pressure has formed adiamond which is a billion billion carats.) planets are different. although they may be made of gas, likejupiter, they are different gases to the ones in stars. also, it is actually very unlikely that it is madefrom gases. it is usually molten iron and rock.A star is a burning mass of (mainly) hydrogen and helium. The outer planets are also made out ofhydrogen and helium. Neptune and Uranus theirs also have methane,hydrogen, and helium in it thatswhy both planets are blue.A planet is a body which moves in an orbit around a star.A planet (of any sort, dwarf or other) is defined as "any celestial body which orbits a star." The earth isa planet.A star is typically a big, burning, ball of gas around which planets tend to orbit. (except when it goesout, then it is a black hole or a neutron star.) The sun is a star.Read more:
