EXPLANATION:

STATEMENT 2 AND 3 ARE INCORRECT. Apart from Pluto other dwarf planets are Ceres Eris Makemake etc. Density of Jupiter and Earth is 1.33 gm/cm3 and 5.517 gm/cm3 respectively.

It is believed that the formation of moon is an outcome of 'giant impact' or what is described as 'the big splat'. A body of the size of one to three times that of mars collided into the Earth sometime shortly after the earth is formed. Age of moon is about 4.44 billion years while that of Earth is approximately 4.6 billion years.
In 2006 the international Astronomical Union decided to shift Pluto into the category of ‘dwarf planet’. A dwarf planet is an object in orbit around the Sun that is large enough (massive enough) to have its own gravity pull itself into a round (or nearly round) shape. Generally a dwarf planet is smaller than Mercury.
A dwarf planet may also orbit in a zone that has many other objects in it. Apart from Pluto other dwarf planets are Ceres Eris Makemake etc.
Jupiter is a gaseous planet while earth is made up of rocks. Density of Jupiter and Earth is 1.33 gm/cm3 and 5.517 gm/cm3 respectively.
