Ayé  Astronomical symbol of Earth
A planetary disk of white cloud formations, brown and green land masses, and dark blue oceans against a black background. The Arabian peninsula, Africa and Madagascar lie in the upper half of the disk, while Antarctica is at the bottom.

Akiyesi[àtúnṣe | àtúnṣe àmìọ̀rọ̀]

  1. All astronomical quantities vary, both secularly and periodically. The quantities given are the values at the instant J2000.0 of the secular variation, ignoring all periodic variations.
  2. 2.0 2.1 aphelion = a × (1 + e); perihelion = a × (1 - e), where a is the semi-major axis and e is the eccentricity.
  3. The reference lists the longitude of the ascending node as -11.26064°, which is equivalent to 348.73936° by the fact that any angle is equal to itself plus 360°.
  4. The reference lists the longitude of perihelion, which is the sum of the longitude of the ascending node and the argument of perihelion. That is, 114.20783° + (-11.26064°) = 102.94719°.
  5. Due to natural fluctuations, ambiguities surrounding ice shelves, and mapping conventions for vertical datums, exact values for land and ocean coverage are not meaningful. Based on data from the Vector Map and Global Landcover datasets, extreme values for coverage of lakes and streams are 0.6% and 1.0% of the earth's surface. The ice shields of Antarctica and Greenland are counted as land, even though much of the rock which supports them lies below sea level.
