The planet Earth is closer to the sun than five other planets. The planet closest to the sun is Mercury followed by Venus and then Earth.
the planet which completes its journey first is mercury i think
Mercury is not the coldest planet because it has more solar radiation than all of the other planets. This is because it is closer to the Sun. However, Mercury is not the hottest planet in the Solar System. See related question.
If you mean "planet", Venus gets closer than any other planet. However, since the distance to the planets varies, both Mars and Mercury, can sometimes be closer than Venus.
Mercury is closer to the Sun than any other. Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system.
There is no planet that can be described as "about as far" from the Sun as Mercury. It's the planet closest to the Sun, and the only other planet closer to the Sun than Earth is Venus, which is about twice the distance away from the Sun compared to Mercury. Considering that's a difference of roughly 51,000,000 km (0.32 AU, 1 AU is the average distance from the Earth to the Sun), that's one hell of a long way away. Still, it's closer than any other planet (however, even the Sun is closer to Mercury than Venus).
Mercury and Venus are closer to the Sun than Earth.
2. Mercury and Venus. All other planets are past the earth.
No, Mercury does not have a twin planet. It is the smallest and innermost planet in our solar system, and there is no other planet that is exactly like Mercury in terms of its size, composition, and distance from the Sun.
Mercury
Mercury is the smallest planet in our solar system. It has a very thin atmosphere mostly made up of oxygen, sodium, hydrogen, helium, and potassium. Mercury has extreme temperature variations between its day and night sides. It has no moons or rings.
Mercury receives the most light from the sun because it is the closest planet to the sun. Being closer means it receives more sunlight, leading to higher levels of solar energy reaching its surface compared to other planets.
