To have life similar to Earth;s a planet would require:
1. Water
2. Plant life (Oxygen)
3. A stable food supply
4. Land and gravity
Other forms of life based on materials such as silicon might require other sources of energy. Even on Earth some life runs on Chemosynthesis using sulfides as an energy source, not Photosynthes based on light energy.

(Unless the planet is Venus, Jupiter, Saturn, Uranus, or Neptune, which have no
water or life. And except for Mercury and Mars which have no water, air or life.
Except for those, the first answer is accurate.)

Space object that was reclassified as a dwarf planet in 2006?
Pluto was reclassified as a dwarf planet in 2006. Pluto was regarded as a planet from its discovery in 1930 until 2006. As Pluto only meets two of the three requirements for the planet classification, it is not considered a planet anymore.
What are the three basic requirements for a satellite?
The three basic requirements for a satellite are: Proper elevation, Proper speed, and Proper orbit. If a satellite does not have these three things it will either float into space or crash into the earth.
Planets with three moons?
Pluto has three moons but is no longer classified as a planet.
What three things must a planet have to be a planet?
To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.
Which planet fits into all three categories?
Saturn fits into all three categories

Why would Pluto never be a planet?
Plutos not a planet because is does not meet the necessary requirements to be a planet
Should Pluto still be a planet?
no because it doesnt have all the requirements for a planet to have
Are scientists thinking about to make Pluto planet?
No, they are not. Pluto doesn't meet all of the requirements to be considered a planet.
Why is Pluto called a dwarf planet andnot a real planet?
Pluto is now classified as a dwarf planet as the requirements for classification as a planet have changed and Pluto is now too small to be a planet
Why is planet mercury a planet?
According to the International Astronomical Union, a planet is an astronomical body orbiting a star or stellar remnant thatis massive enough to be rounded by its own gravity,is not massive enough to cause thermonuclear fusion, andhas cleared its neighbouring region of planetesimals.Mercury meets all three requirements and so, by definition, it is a planet.

State four requirements needed to be considered a planet?
It has to have enough gravity to force itself into a spherical shape, it has to orbit a "parent star" and has to have an elliptical orbital path.
