Pluto is about half the size of Mercury, which is the smallest "true" planet.
Mercury is, by far the smallest.Its average diameter is 4879 km compared to 6792 km for the next smallest, Mars, and compared to 142,984 km for Jupiter.
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
Mars is the second smallest planet. Only Mercury is smaller.

Yes, all of the dwarf planets are smaller than the smallest inner planet (Mercury).
No, the moon is relatively larger compared to the moons of other terrestrial planets. It is the fifth largest moon in the solar system, with a diameter about one-quarter that of Earth. Other terrestrial planets, such as Mars and Mercury, have smaller moons in comparison.
Mercury ,venus ,earth and mars
There are probably several things Mercury has very little of, but compared to the other planets is has very little size/mass and very little distance from the sun.
The terrestrial planets are Mercury, Venus, Earth, and Mars. They are characterized by their solid surfaces, rocky composition, and relatively smaller size compared to gas giants like Jupiter and Saturn.
Jupiter is the largest planet in our solar system, while Mercury is the smallest. Jupiter is known for its massive size and strong gravitational pull, while Mercury is the closest planet to the Sun and has a relatively small and compact size compared to the other planets.
Mercury has the largest core relative to its overall size among the terrestrial planets. The core makes up about 85% of Mercury's radius, compared to about 55% for Earth's core size relative to its radius.
