No. No two planets have the same size orbit. Mars orbits the sun at more than twice the distance that Venus does.
The two planets that are closest in size to Earth are it's neighbours: Venus and Mars. Of the two, Venus is nearly the same size, with a diameter of 12,104km (compared to Earth's diameter of 12,756km). Mars is smaller - almost half the size of Earth - with a diameter of 6792km.
Mars is the second-smallest major planet (Only Mercury is smaller).Planets in order of size, smallest to largest :MercuryMarsVenusEarthNeptuneUranusSaturnJupiter(see related link)
yes there is 2 planets but there are also dwarf ones too.
Larger than: -Mercury -Mars -Pluto (I know it isn't a planet anymore!) Same size as: -Earth Smaller than: -Jupiter -Saturn -Uranus -Neptune
This is a function of distance - an object appears smaller the further away it is. Although Jupiter is many times the size of Mars, the two planets appear to be about the same size because Jupiter is also much further away from Earth than Mars is.
Mars is the second smallest planet. Only Mercury is smaller.
Its Equatorial radius about 3,396.2 Km which makes it 0.533 Earths.See the photo of (from left to right) Mercury, Venus, Earth, and Mars to scale:
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
Compared to some other planets in the same galaxy, yes; it is actually fractions of the size of other planets in this galaxy
The 'little planets' between Mars and Jupiter are called asteroids.
The planets of our solar system are most definitely NOT all the same size.
