The largest planet orbiting Sol (our Sun) is Jupiter. Its mass is 1.8986×1027 kg, about the size of 317 Earths.
If by last largest, you mean least largest or smallest, then Mercury holds that distinction. (Pluto is disqualified) If by last largest, you mean largest, then that would be Jupiter. This answer also makes the assumption that you are only interested in planets orbiting Sol.
Jupiter
Jupiter is the largest planet in our solar system, but not the largest planet of all. Planets larger than Jupiter have been found orbiting other stars.
Venus is a terrestrial planet orbiting the star Sol. It is composed mainly of sulfur, carbon, and iron.
The largest dwarf planet in the solar system is Pluto, and it is also the ninth largest body orbiting the sun directly. Pluto was reclassified as a dwarf planet by the International Astronomical Union in 2006.
Mercury - (Sol I) - Closest planet to the Sun Venus - (Sol II) - Known for its thick atmosphere Earth - (Sol III) - Our home planet Mars - (Sol IV) - Often called the "Red Planet" Jupiter - (Sol V) - Largest planet in our solar system Saturn - (Sol VI) - Known for its distinctive rings Uranus - (Sol VII) - Tilted on its side Neptune - (Sol VIII) - Farthest planet from the Sun
The only natural satellite orbiting Earth is the moon.
Venus is the biggest planet in our solar system that has no known satellites (moons).
No. Jupiter is the largest planet in our solar system (the sun is a star, not a planet), but not the largest in existence. Planets larger than Jupiter have been found orbiting stars other than the sun.
Saturn is the second largest planet in the solar system and has an extensive orbiting ring system.
Mercury is the largest terrestrial planet without a moon. It is the smallest of the eight planets in our solar system and does not have any natural satellites orbiting around it.
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
