La masa terrestre o masa de la Tierra (M 🜨) es una unidad de medida de masa utilizada en astronomía y astrofísica para medir comparativamente la masa de los planetas, exoplanetas y otros objetos astronómicos poco masivos, tales como los asteroides o planetas enanos . Es equivalente a la masa de la Tierra (M 🜨 = 3,9722 × 10 21 kg, 1 2 ...
Earth's mass is approximately 5.97 × 10 24 kg (5,970 Yg). It is composed mostly of iron (32.1% by mass), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.

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.
In astronomy, planetary mass is a measure of the mass of a planet -like astronomical object. Within the Solar System, planets are usually measured in the astronomical system of units, where the unit of mass is the solar mass ( M☉ ), the mass of the Sun.
