The current best estimate for the mass of Earth is M 🜨 = 5.9722 × 10 24 kg, with a relative uncertainty of 10 −4. It is equivalent to an average density of 5515 kg/m 3. Using the nearest metric prefix, the Earth mass is approximately six ronnagrams, or 6.0 Rg.

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection . Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth.
Massachusetts is the sixth-smallest state by land area. With over seven million residents as of 2020, [note 1] it is the most populous state in New England, the 16th-most-populous in the country, and the third-most densely populated, after New Jersey and Rhode Island. Massachusetts was a site of early English colonization.

An Earth mass (denoted as or , where 🜨 is the standard astronomical symbol for Earth ), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is M🜨 = 5.9722 × 1024 kg, with a relative uncertainty of 10 −4. It is equivalent to an average density of 5515 kg/m3.
Earth's average density can be determined through gravimetric experiments, which have historically involved pendulums. The mass of Earth is about 6 × 10 24 kg. The average density of Earth is 5.515 g/cm 3. Layers. The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically.
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. [4] [5] [6] Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
