No.
A planet.
Type your answer here... if a planet breaks any of these 3 rules it becomes a dwarf planet is in orbit around the sun has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and has "cleared the neighbourhood" around its orbit
Planet Venus cannot leave its orbit by itself. A sufficiently close encounter with a object of sufficient mass will perturb its orbit. If the object is large enough and close enough, Venus (or any planet) could leave the orbit of the Sun.
Too small. (To be even a dwarf planet you must have sufficient mass to give yourself a spherical shape.)
The 2006 (re)definition of a planet includes three criteria - 1) it is in orbit around the Sun, 2) it's achieved hydrostatic equilibrium (characterized by sufficient mass to have a rounded shape), 3) it has cleared the area around it orbit. Under this last criteria, Pluto, formerly considered a planet, is now classified as a dwarf planet as it has only cleared a tiny fraction of its orbit.
Sufficient for your requirements.

In 2006, a planet became defined as a body orbiting the Sun that has a mass of self gravity sufficient enough to make it nearly round, and has a clear orbit. A+ planet
Because it has sufficient gravity and a strong magnetosphere.

The mass of the planet. It's not clear cut, since there has to be gas around in the area to provide the atmosphere, but the planet (or moon) need to be massive enough to provide sufficient gravity for the gas molecules not to escape into space.

is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite. it has to have sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium. It should not be confused with a minor planet.
It is because it gives us the knowledge to progress mankind but in a more civilised and sufficient way than our ways here on planet earth.
