For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
13 things in the gigameter group Upper part: Gamma Orionis, Algol B, the Sun (centre), and other objects to scale. The gigametre (SI symbol: Gm) is a unit of length in the metric system equal to 1 000 000 000 meters (10 9 m). To help compare different distances this section lists lengths starting at 10 9 meters (1 gigameter (Gm) or 1 billion ...
Bosons are one of the two fundamental particles having integral spinclasses of particles, the other being fermions. Bosons are characterized by Bose–Einstein statistics and all have integer spins. Bosons may be either elementary, like photons and gluons, or composite, like mesons. According to the Standard Model, the elementary bosons are:
Particle size is a notion introduced for comparing dimensions of solid particles , liquid particles , or gaseous particles . The notion of particle size applies to particles in colloids , in ecology , in granular material (whether airborne or not), and to particles that form a granular material (see also grain size ).
While macroscopic systems indeed have a larger total energy content than any of their constituent quantum particles, there can be no experiment or other observation of this total energy without extracting the respective amount of energy from each of the quantum particles – which is exactly the domain of high energy physics. Daily experiences ...
A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide). [1] The constituents that compose granular material are large enough such that they are not subject to thermal motion fluctuations.

The result of all the particles settling in a different order may be an increase in the potential energy—a raising of the center of mass. When shaken, the particles move in vibration-induced convection flow; individual particles move up through the middle, across the surface, and down the sides. If a large particle is involved, it will be ...
