Planets, on the other hand, are observed to move in very complicated paths with respect to the background stars, sometimes even appearing to go "against the grain" and reverse their directions. Therefore, they are easily distinguishable from stars if you look at the sky night after night. the objects which exist in the sky are called celestial objects. the star the planet satellites these are the celestial objects that are extremely hot and have light of their own..they emit heat and light continuously.it consists mostly of hydrogen gas .the heat and light produced in the star takes place by the nuclear fusion reaction taking place inside them the sun
why does pole star appear stationary in the sky
it is because it lies on the axis of rotation of earth which is fixed in space and does not change with time
do all stars in the sky move?explain?
no, the earth rotates from west to east on its axis hence all stars except pole star appear to move from east to west.since the pole star lies on tthe axis of the earth so it appears to remain stationary at one point in the sky

these are the large celestial objects which revolves around the sun in cosed elliptical paths called orbits. there are 8 planets in the solar system mercury venus earth mars jupiter saturn uranus Neptune. the first planets -mercury,venus.earth,mars are very close to the sunthey are made of rocks and have metallic cores.they are small and dense bodies .they have few natural satellites the planets outside the orbit of mars are called outer planets-jupiter,saturn,uranus and neptune.they are made of hydrogen and helium gases.they donot have solid surfaces.the outer planets have ring system around themthey have large number of satellites around them
why is it difficult to observe the planet mercury
since mercury planet is close to the sun so it is hidden by the suns glare and is thus difficult to see the stars twinkle in the night sky but the planets do not twikle at all
