Earth is the fifth largest of the eight planets of the Solar System
among the eight planets of our solar system, from largest to smallest, yes
Jupiter is the largest of the 8 major planets, and the largest body in the solar system except for the Sun itself.
Jupiter is the largest planet among the four planets closest to the sun, which are Mercury, Venus, Earth, and Mars.
They are all bigger
No, comets are generally much smaller than planets. Comets are composed of ice, dust, and rocky materials and can range in size from a few hundred meters to tens of kilometers in diameter. In comparison, planets are much larger celestial bodies that orbit stars and have a defined spherical shape.
Pluto is smaller in size compared to the other planets in our solar system. It is classified as a dwarf planet, with a diameter that is smaller than Earth's moon. Among the eight recognized planets, Pluto ranks the smallest.
Pluto is smaller than the eight major planets. It is the second-largest "dwarf planet" in the solar system (only Eris appears to be larger).
All of the inner planets are rocky planets: Mars, Earth, Venus, and Mercury
The size of a black dwarf is about the same as some planets. They are expected to range in size from a little less than Earth's diameter to twice Earth's diameter.
Solid objects that can orbit planets are called moons. Moons are natural satellites that orbit around planets in a similar way that planets orbit around stars. Moons can range in size from small rocky bodies to larger worlds with their own atmospheres.
But you CAN determine the size of the planets: in diameter, overall mass, and in density.
