UFO. Netherlands

The balloon (simplified is a balloon) — an aircraft lighter than air, where the lift force is used enclosed in a sheath gas (or heated air) with a density less than the density of the surrounding air.

Distinguish between tethered, Svobodnaya and balloons — powered airships.

The brightest heavenly bodies in the sky are Venus, Jupiter, and sometimes Mars and, of course, the Moon.

Venus is the bright yellow of the evening or morning star, shining in the sky on the background of evening or dawn. Maximum brightness of Venus can reach up to 4.3 m, and she is the third brightness of the sun in earth's sky after the sun and the moon. It so well reflects the light of the Sun that it is relatively easy to see and day, especially if you know the location. It manifests itself in the form of tiny blinking white dots.

Ordinary satellites, which often look like single, not very bright luminous dots moving smoothly in the night sky, are quite often mistaken for UFOs. After the Starlink satellites (near-Earth satellite systems developed by SpaceX, in order to create a cheap and high-performance satellite Internet communication channel and technical transmitters for receiving and transmitting signals from earth and orbit) were launched, it became possible to observe groups of satellites (up to 60 pieces) flying one after another.
