<ref name=apsis>aphelion = ''a'' × (1 + ''e''); perihelion = ''a'' × (1&nbsp;– ''e''), where ''a'' is the semi-major axis and ''e'' is the eccentricity. The difference between Earth's perihelion and aphelion is 5 million kilometers.</ref>

<ref name=epoch>All astronomical quantities vary, both [[Secular phenomena|secularly]] and [[Frequency|periodically]]. The quantities given are the values at the instant [[J2000.0]] of the secular variation, ignoring all periodic variations.</ref>

<ref name=hill_radius>For Earth, the [[Hill radius]] is <math>R_H = a\left ( \frac{m}{3M} \right )^{\frac{1}{3}}</math>, where ''m'' is the mass of Earth, ''a'' is an astronomical unit, and ''M'' is the mass of the Sun. So the radius in AU is about <math>\left ( \frac{1}{3 \cdot 332,946} \right )^{\frac{1}{3}} = 0.01</math>.</ref>

<ref name=sidereal_solar>The number of solar days is one less than the number of [[sidereal day]]s because the orbital motion of Earth around the Sun causes one additional revolution of the planet about its axis.</ref>

<ref name=solar_energy>Aphelion is 103.4% of the distance to perihelion. Due to the inverse square law, the radiation at perihelion is about 106.9% the energy at aphelion.</ref>

<ref name=surfacecover>Due to natural fluctuations, ambiguities surrounding [[Ice shelf|ice shelves]], and mapping conventions for [[vertical datum]]s, exact values for land and ocean coverage are not meaningful. Based on data from the [[Vector Map]] and [http://www.landcover.org/ Global Landcover] {{Webarchive|url=https://web.archive.org/web/20150326085837/http://www.landcover.org/ |date=2015-03-26 }} datasets, extreme values for coverage of lakes and streams are 0.6% and 1.0% of Earth's surface. The ice shields of [[Antarctica]] and [[Greenland]] are counted as land, even though much of the rock that supports them lies below sea level.</ref>

<ref name=trench_depth>This is the measurement taken by the vessel ''[[Kaikō]]'' in March 1995 and is considered the most accurate measurement to date. See the [[Challenger Deep]] article for more details.</ref>
