Solar system vs 💀.#space #universe #vutrubaolaa

It was not until 1950 that people were able to measure the speed of light, thousands of years after the Giza pyramid was completed. So why could the ancients know? #space #universe #vutrubaolaa

The smallest planet in our solar system and closest to the Sun—only slightly larger than Earth's Moon. Its surface is covered with tens of thousands of impact craters. From Mercury's surface, the Sun will be three times larger than when viewed from Earth, and sunlight will be up to 11 times brighter. Despite its close proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus thanks to its dense atmosphere. But Mercury is the fastest planet, orbiting the Sun every 88 Earth days. Mercury was appropriately named for the fastest god of ancient Rome. #space #universe #vutrubaolaa

ζ Ori (Alnitak), ε Ori (Alnilam), and δ Ori (Mintaka). Alnitak is about 800 light years from Earth, including ultraviolet radiation that the human eye cannot see, Alnitak is 100,000 times brighter than the Sun. Alnilam is about 1340 light years from Earth with a stellar magnitude of 1.70. Considering ultraviolet light, Alnilam is 375,000 times brighter than the Sun. Mintaka is 915 light years from Earth with a stellar magnitude of 2.21. Mintaka is 90,000 times brighter than the Sun. Mintaka is a double star. These two stars orbit each other once every 5.73 days. Observing Orion's belt is the easiest way to identify the constellation Orion in the night sky. In the Northern Hemisphere, Orion's Belt is best seen around 9:00 p.m. in January. #space #universe #vutrubaolaa
