Planets are not stars. On casual observation, both planets and stars appear as bright dots in the night sky. But with careful observation, we know planets are different from the stars.
Flat-Earthers insist that planets are just stars. In reality, we can easily observe many of the planets’ attributes that set them apart from the stars —using minimal efforts and equipment.

On Earth, daylight sky is glowing in bright blue due to Rayleigh scattering. Sunlight is scattered in every direction by the oxygen and nitrogen molecules in Earth’s atmosphere.
Such the phenomenon does not happen on the Moon, causing the dark sky of the Moon. Flat-Earthers claim that the dark sky of the Moon captured by photos and videos taken from the Moon are “proof” there is misconduct. They are wrong. Just because Earth’s sky is bright blue, it does not mean it will be like that on the Moon and other planets.

The distance to the Sun was first determined with a good accuracy from worldwide observations of the transit of Venus. A transit of Venus is a phenomenon where Venus passes in front of the Sun. By measuring the time Venus spends crossing in front of the Sun from two or more locations on the surface of the Earth, it is possible to calculate the distance to the Sun.
Flat-Earthers insist that it is impossible to determine the distance to the Sun in the globe model because sun rays are practically parallel. They are wrong. Using simple geometry, the distance to the Sun can be determined from the observations of the transit of Venus.

Mercury and Venus are closer to the Sun compared to the Earth. The best condition to observe these planets is during some time after sunset or before sunrise. In some cases, they are even visible in the day.
Many flat-Earthers think that it should be impossible to observe Mercury & Venus as they are closer to the Sun. They are wrong.

The topic of tide come up frequently in the flat-Earth community. Let’s examine some of the ‘issues’ they brought up about tides in Q&A format.

The Nikon Coolpix P900 camera is a very popular camera among flat-Earthers because there’s no other compact camera ever made that has such enormous zoom range. It is a unique and a very useful tool in this state of affair.
Someday, some flat-Earthers decided to bring their trusty P900s out and used them to take some pictures of Venus. To their delight, the resulting pictures don’t look like Venus we all used to know. They were too excited that they thought they have discovered an original ‘proof’ of global deception. “This is an irrefutable ‘proof’ that they have been lying to us!” so they say.
But, maybe there’s a simpler, more plausible explanation…
