While it is unclear which four choices you have, since there are only eight planets, they can all be listed in the order of size and you can determine which one is the largest of those:
The 4 largest planets in order from biggest to smallest are:JupiterSaturnUranusNeptune
Neptune > Earth > Mars > Mercury Largest ---> Smallest
The 4 largest planet in our solar system are Jupiter , Saturn , Uranus, and Neptune
Jupiter is the largest planet among the four planets closest to the sun, which are Mercury, Venus, Earth, and Mars.
In order they are : Mercury , Venus , Earth , Mars.
The largest objects that orbit the sun are planets.
Of the planets within our own solar system, Venus is 6th largest out of eight planets.
Your question is confusing but when you say "the two largest planets" I'm thinking you are talking about Saturn and Jupiter, the largest planets in our solar system. So I think my answer is our sun.
The largest planets are the four gas giants, which are Jupiter, Saturn, Uranus and Neptune.
From largest to smallest, the planets in our solar system are:JupiterSaturnUranusNeptuneEarthVenusMarsMercury.Ganymede (a moon orbiting Jupiter) and Titan (Saturn's moon) are bigger than Mercury.There are many more large planets outside the solar system.
Venus and Earth are called "Sister planets" but if you've noticed Venus is bigger than Earth so therefore Venus is the biggest planet.
Jovian planets are: -gaseous -farthest planets from the sun -largest planets
