The two smallest major planets, Mercury and Mars, are both smaller than the estimated size of the Earth's core (combined inner and outer core).
Mercury has a diameter of about 4879 km and Mars is about 6792 km, compared to the Earth's core which is a sphere about 6972 km in diameter.
All of the dwarf planets (Pluto, Eris, Haumea, Makemake, and Ceres) are smaller in diameter than even the Earth's solid inner core (~2440 km in diameter), although Eris is almost as large and Pluto only slightly smaller than Eris.
-The Earth's inner core has a thickness (radius) of about 1220 km.
-The Earth's outer core has a thickness (radius) of about 2266 km.

Which planet is slightly smaller than the Earth's core?
Mercury is slightly smaller then the Earths Core. Mercury is believed to have been struck by a planet sized object billions of years ago which blew away everything but the core of the planet.(If Pluto was still a planet, Pluto would also be smaller than the Earth's core, but it was demoted to the status of a dwarf planet.)
Which other planet in the solar system closest in size to the earth?
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
