There are various objects in the universe , from microscopic to macroscopic which are of different shapes and sizes. Apart from the sizes of what we see daily, look at these mind boggling sizes of various elements which exists at this very moment in our universe.

Neon atom: 7.6*10-11 meters

Carbon atom:  1.34*10-10 meters

Neodymium atom: 4.12*10-10 meters

Neodymium (Nd). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of neodymium-144 (atomic number: 60), an isotope of this element. The nucleus consists of 60 protons (red) and 84 neutrons (orange). 60 electrons (white) successively occupy available electron shells (rings). Neodymium is a lanthanide in period 6, and the f-block of the periodic table. It melts at 1024 degrees Celsius. The trend across the lanthanide series arises from the failure of electrons filling an inner f-subshell (here, within the 4th ring) to shield outer (valence) electrons from increasing nuclear charge.

Cat’s eye nebula – Made from central star: 0.2 Light years

This gallery shows four planetary nebulas from the first systematic survey of such objects in the solar neighborhood made with NASA’s Chandra X-ray Observatory. The planetary nebulas shown here are NGC 6543 (aka the Cat’s Eye), NGC 7662, NGC 7009 and NGC 6826. X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue. A planetary nebula is a phase of stellar evolution that the sun should experience several billion years from now, when it expands to become a red giant and then sheds most of its outer layers, leaving behind a hot core that contracts to form a dense white dwarf star. A wind from the hot core rams into the ejected atmosphere, creating the shell-like filamentary structures seen with optical telescopes. The diffuse X-ray emission is caused by shock waves as the wind collides with the ejected atmosphere. The properties of the X-ray point sources in the center of about half of the planetary nebulas suggest that many central stars responsible for ejecting planetary nebulas have companion stars.
