they are less than
Mercury, Venus, Earth, Mars, Neptune and Pluto.
Saturn. This is untrue. Both Mercury and Venus have shorter orbits and therefore take less time to orbit the Sun, because they are the two planets closer to the Sun then Earth. Saturn is further from the Sun and takes much longer to orbit it.
You would seem to weigh less on Mars or on Venus than you do here on Earth, although the environment of Venus would be intolerable because of the high temperature and extreme pressures. On Mercury you would weigh much less, but the heat there is intense.
It can be sometimes, but Venus can be closer than Mercury ever can; Mercury is only the closest planet to Earth when Venus is on the opposite side of the Sun from Mercury and Earth, and maybe not even then (depending on exactly where Mars is).
Mercury and Venus
They are less than 1 AU from the sun.
Mercury and Venus take less time to complete one orbit of the sun, since they are closer to the sun. They have less distance to travel, and are orbiting at a greater tangential speed.
Mercury and Venus.
Mercury, Venus, and Mars.
No, it has much less mass.
Mercury is much closer to the sun than Venus. It has less of an atmosphere, much higher temperatures, and a very short year. Venus has an very sulfur-rich atmosphere, cooler temperatures than Mercury, and a longer year than Mercury.
No, Venus is bigger than mercury
Mercury and Venus take less time to orbit the Sun than the Earth does. ummm...if you need 5 then...earth, venus, mercury, mars and jupiter
Mercury is hotter than Venus and Venus is brighter than Mercury
Mercury and Venus.
Venus is hotter than Mercury because Venus has a atmosphere and Mercury doesn't so Mercury can't keep so much heat in as Venus can.
Venus is hotter than Mercury because Venus traps heat and cannot escape from the Sun in the atmosphere.
