⭐️ Black hole Facts⭐️ ✨Gravity is so strong in Black holes that it sucks everything in, including light. ✨If a human fell in to Black hole, they would stretch like spaghetti. ✨When a star or Galaxy becomes so dense that is collapses under the pull off its own gravity, Black holes created. ✨Gravity shrinks a Black hole to unimaginably small point called singularity. ✨Around a singularity, is so dense that space-time is bent into a funnel. ✨Matter spiralling in to a Black hole is torn apart and glows so brightly that it creates the brightest objects in the universe quasars. ✨The swirling gases around a Black hole turn in to electrical generator, spouting jets containing electrons that are billions of kilometers out in to space. ✨The opposite of black holes may be white holes, which spary out matter and light like fountains. ✨Black holes and white holes may join to form tunnels called worm holes. ✨The gravity of a black hole is so strong that nothing can escape, not even light. Planets, stars, gas and dust are pulled in to the hole. @LAQMC

🌔Venus🌖 ✨The second planet from the sun is Venus. It orbit makes it 107.4 million km away at its nearest and 109 million km at furthest. ✨Venus shines like a star in the night sky because it thick atmosphere reflects sunlight amazingly well. This planet is the brightest objects in the sky, after the Sun and Moon. ✨Venus is called the Evening Star because it can be seen from Earth in the evening, just after sunset. However, it can also be seen before sunrise. It is visible at these times because it is quite close to the sun. ✨The atmosphere of Venus is mostly carbon dioxide gas with thick clouds containing sulphuric acid, given out by the planet's volcanoes. ✨The atmosphere reflect sunlight and make the planet shine like a star. None of its atmosphere is transparent like the Earth's, which make it very difficult to see what is happening on the planet's surface. ✨The 6 km high volcano on the surface of Venus is called Maat Mons. ✨Venus is the hottest planet in the Solar System, with a surface temperature of more than 470 degree C. ✨Venus is so hot because the carbon dioxide in its atmosphere traps the Sun's heat. This overheating is called is called a runaway greenhouse effect. ✨The thick cloud hides its surface so well that until the Russian Venera 9 probe landed on the planet in 1975, it was not known what was beneath the clouds. ✨Pressure on the surface of Venus is 90 times greater than that on Earth. ✨A day on Venus(the time it takes to spin around once) lasts 243 Earth days-longer than it's year, which lasts 224.7 days. ✨ As Venus rotates backwards, the sun comes up twice during the planet's yearly orbit- once every 116.8 days. ✨Venus is the nearest planet to Earth in size, measuring 12, 102 km in diameter. @LAQMC

🌔Mercury🌖 ✨The nearest planet to the sun is Mercury. During its orbit, it is between 45.9 and 69.7 million km away. ✨Mercury has the fastest orbit- it orbit around the Sun takes just 88 Earth days. ✨Twice during its orbit, Mercury gets very close to the sun and speeds up so much that the sun seems to go backwards in the sky. ✨Mercury rotates once every 58.6 days, but the time between one sun rise and the next is 176 days, longer than it's year. ✨Temperature change from -180 degree C at night to more than 430 degree C during the day(hot enough to melt lead). ✨The crust and mantle are made largely of rock, but the core(75% of its diameter) is solid iron. ✨Mercury dusty surface is pocketed by craters made by space debris crashing in to it. ✨With 6% of Earth's mass, Mercury is so small that its gravity can only hold on to a thin atmosphere. ✨The sun looks huge as it rises over Mercury. The sunny side of the planet is boiling hot, but the night side is more than twice as cold as Antarctica. ✨Mercury is so small that its core has cooled and become solid(unlike Earth's). As this happened, Mercury shrank and its surface wrinkled. ✨Craters on Mercury is discovered by the USA's Mariner 10 space probe have names such as Bach, Beethoven, Wagner, Shakespeare and Tolstoy. ✨Mercury is a planet of Yellow dust, as deeply dented with craters as the Moon. Astronomers thinks that they have found ice in deep craters where the sun never shines. ✨The largest feature on Mercury is a huge impact crater called the caloris Basin, which is about 1300 km across and 2 km deep. ✨Mercury's surface is wrinkled by long, low ridge that probably formed as the planet's core cooled and shrank. @LAQMC
