The earth is a spheroid.

I accept. I will not however, write forfeit in the last round.I'd prefer to write "extend" or "forwarding."Reminder to voters and moderators: Opt-in serves to remove sh*tty votes.

Satellites orbit the Earth.We launch satellites into Earth's orbit by having the satellite hit a critical speed, called the orbital velocity, given the size of the satellite and its distance from the Earth, necessarily a radius.Currently there are over 1,700 satellites orbiting the Earth successfully right now.https://www.ucsusa.org...The equations for orbital speed, acceleration, and period of a satellite necessarily include the average radius of orbit for the satellite or the distance from center of the central planet.http://www.physicsclassroom.com...These equations only work if the central planet is a sphere or spheroid, because as noted, they use a radius to calculate everything...the calculations are working, and you can thank them for your GPS too.How is it that we can accurately calculate and successfully execute getting all of these satellites into Earth's orbit if our calculations are all centered around a spheroid mass and the Earth is flat?The calculations would fail without a central spherical or spheroid body.The moon is also a satellite and for the same reason.Its orbital velocity is proportional to its average radius from the center of the spheroid mass, the Earth, and because earth is round, the moon maintains an average radius about the Earth.2. The Earth is too far along in its planetary formation to be flat.The planets and the sun all formed from a gas rich nebula.Within the nebula, "as gravity pulls material in the collapsing cloud closer together, the center of the cloud gets more and more compressed and, in turn, gets hotter, much of the cloud begins rotating in the same direction, and the rotating cloud eventually flattens into a disk that gets thinner as it spins."http://hubblesite.org...This flat disk is called a protoplanetary disk because it is the beginning, not complete form of a planet.This is really the only time the Earth was ever flat.At every moment after this protoplanetary disk state, gravity and coalescence made the earth very rocky and globular.http://iopscience.iop.org...The Earth is currently about 4.5 billion years old, which is way too old to be in the beginning stages of planetary formation which negates that it is still flat.The Earth is too mature to be a flat protoplanetary disk.https://pubs.usgs.gov...3. All other planets in the solar system formed similarly and are all spheroids.We know that "the Solar System, formed between 4.53 and 4.58 billion years ago" from the same gas rich nebulae with the same process, i.e. collapsing of gas-->protoplanetary disk-->gravitationally dominant spherical mass reaching orbital velocity about the sun.https://pubs.usgs.gov...All of the other planets in our own solar system are spherical or spheroid.Here are *actual* telescope shots of the other planets in the solar system.Notice that every planet is spherical or spheroid.4. Earth's shadow on the moon during a lunar eclipse is round.Here's a video of the Earth's shadow on the moon during a lunar eclipse.Go in to the video at about 53 seconds.What shape is the Earth's shadow?It's round like a sphere or spheroid, just like all other planets and moons in the solar system.
