  2. Molniya orbit - Wikipedia

    en.wikipedia.org/wiki/Molniya_orbit

    In the operational part of the orbit (four hours on each side of apogee), the satellite is north of 55.5° N (latitude of, for example, central Scotland, Moscow and southern part of Hudson Bay). A satellite in this orbits spends most of its time over the northern hemisphere and passes quickly over the southern hemisphere.

  3. Earth's orbit - Wikipedia

    en.wikipedia.org/wiki/Earth's_orbit

    The effect of the Earth's axial tilt in the southern hemisphere is the opposite of that in the northern hemisphere, thus the seasons of the solstices and equinoxes in the southern hemisphere are the reverse of those in the northern hemisphere (e.g. the northern summer solstice is at the same time as the southern winter solstice).

  4. Southern Hemisphere - Wikipedia

    The Southern Hemisphere from above the South Pole The Southern Hemisphere is highlighted in yellow. The hemispheres appear to be unequal in this image because Antarctica is not shown. The Southern Hemisphere is the half ( hemisphere ) of Earth that is south of the equator .

  5. Satellite ground track - Wikipedia

    en.wikipedia.org/wiki/Satellite_ground_track

    In a Molniya orbit, apogee occurs at a high latitude (63°), and the orbit is highly eccentric (e = 0.72). This causes the satellite to "hover" over a region of the northern hemisphere for a long time, while spending very little time over the southern hemisphere.

    In the Southern Hemisphere, this is known as the southern lights, or the aurora australis. A time-lapse of the cosmic pairing also revealed dozens of satellites flickering in the night sky.

    Groundtrack of Molniya orbit. In the operational part of the orbit (4 hours on each side of apogee), the satellite is north of 55.5° N (latitude of for example central Scotland, Moscow and southern part of Hudson Bay). A satellite in this orbits spends most of its time in the northern hemisphere and passes quickly over the southern hemisphere.
