Okay, there are two problems with your question. Firstly, define space. Like, do you mean our solar system, galaxy or the universe in general? Secondly, do you consider Pluto a planet anymore? If you're just talking about the solar system, no. The second smallest planet in our solar system is Mars. This does not include Pluto. The size order of all the planets is: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mercury and then Pluto (if you still consider it a planet). Our galaxy is huge and could contain millions of other planets ranging in size from the size of a pea to the size of a small star. The definition of a planet is spherical object which orbits around a star. Even though our galaxy is huge, there are millions of billions of other galaxies out there, many bigger than ours, so there is no chance that out planet is the second smallest in the universe.
No. Mars is the second smallest planet in the solar system. Saturn is the second largest.
Mercury is the smallest planet closest to the sun, followed by Venus as the second smallest planet. Venus is often referred to as Earth's "sister planet" due to their similar size and composition.
Mercury was listed as the second smallest planet. Since Pluto lost its status as a planet Mercury is now the smallest planet.
Mercury is now the smallest 'true' planet in our solar system. Pluto was the smallest planet before the definition of a planet was revamped. Now, if you include dwarf and minor planets, the next biggest is Eris.
Mars is the second smallest planet, Mercury is the smallest.

Mars is the second smallest planet and Mercury is the nearest to the Sun.
The smallest is Mercury, the second smallest is Mars.
Earlier, Pluto was the smallest planet and Mercury was next.Now, Mercury is the smallest planet and hence, Mars is the second smallest.Now that Pluto has been reclassified as a dwarf planet, the second smallest is Mars. Before Pluto was reclassified as a dwarf planet, Mercury was the second smallest planet.The second smallest planet in the solar system is Mars with a diameter of 4,221.6 miles.Mars is the 2nd smallest planet, Mercury is the smallest.Mercury
Mars is the second smallest planet. Only Mercury is smaller.
No, it is the second smallest. Mercury is the smallest.
Pluto is a dwarf planet, so if you include Pluto, Mercury is the second smallest. if you don't, Mars is the second smallest
Mars is the second smallest after Mercury.
