Bus-Sized Asteroid Buzzes Earth in Harmless Flyby! Get ready for some out-of-this-world news! Today, an asteroid named 2024 DW, roughly the size of a city bus, is making a close flyby of Earth, even closer than the Moon's orbit. But don't worry, space fans, this celestial visitor is no cause for alarm. Here's the scoop: Size:About 30 meters in diameter, comparable to a school bus. Distance: Will skim past our planet at a safe distance of approximately 3,400 kilometers (2,100 miles), closer than some communication satellites. Time: The closest approach is expected around [time asteroid is closest to Earth], so keep your eyes peeled towards the sky (if you have a powerful telescope!). Risk: None! This asteroid poses absolutely no threat to Earth or its inhabitants. This flyby is a reminder of the amazing celestial ballet that takes place in our solar system. While most asteroids orbit peacefully in the asteroid belt between Mars and Jupiter, some occasionally nudge closer to our planet. These flybys offer valuable opportunities for astronomers to study these rocky visitors, gleaning insights into their composition, origins, and potential hazards. #asteroid #flyby #spacenews #earth #astronomy #science #snsinstitutions #snsdesignthinkers #designthinking

Pluto is not considered a planet. In the past, it used to be but around 2006, the contours of what constitutes a planet were changed and its status as a planet was revoked on August 24, 2006. Under the International Astronomical Union (IAU), Pluto is classified as a ‘dwarf planet’ and not as a proper planet. This is because there is a considerable number of rocks and asteroids in the flight path to Pluto, which, unlike other planets, has not absorbed. According to the IAU, a planet is a celestial, spherical body that orbits around the Sun and has mostly absorbed objects such as asteroids and rocks from its orbit. Pluto’s demotion has remained controversial because there are examples that do not fit neatly into these classifications. This also shows the limitations of any classification and the principle that nothing is ever completely certain when producing and reproducing knowledge. Pluto due to its small size and freezing temperatures, however, offers a wealth of information about non-Earth planets in space and the different conditions and phenomena they display.

https://buff.ly/3rimLG0 This September, after traveling billions of miles through our solar system, NASA’s OSIRIS-REx spacecraft will cruise past Earth with an extraordinary delivery. As it passes, it will release a mini-fridge size capsule containing a sample of primordial space rock collected from an asteroid located between the orbits of Earth and Mars. OSIRIS-REx — the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer — is the first U.S. mission to collect a sample from an asteroid. Scientists hope the pristine material it collected from asteroid Bennu in 2020 — about half a pound of rubble and dust from the asteroid’s surface — will provide a window into 4.5 billion years ago when the Sun and planets were forming. Before it can do that, the sample’s protective capsule will withstand temperatures twice as hot as lava, and the second-fastest velocity ever achieved by a human-made object entering Earth’s atmosphere. After entering Earth’s atmosphere at around 36 times the speed of sound, the capsule may eventually encounter wind, rain, and other weather conditions as it drops closer to the surface. Regardless of weather, it will land in the Great Salt Lake Desert, an arid landscape known for its scorching summer temperatures and its salt flats, the remnants of an ancient lakebed where crusty salt deposits coat the ground. While much of the focus will be on the technical aspects of the spacecraft and the landing capsule, a team of scientists and meteorologists will also be closely monitoring the weather, which can significantly affect recovery of the capsule.

A family of primitive asteroids is providing astronomers with a window into the past as they seek to unravel the history of these small space rocks believed to have once brought water to Earth. Life in the solar system can be dangerous, with lots of impacts having taken place over the course of history — for instance, consider the giant impact that formed our moon or the many impacts that spurred the cratered surface of Mercury. On occasion, large asteroids in the main asteroid belt, located between Mars and Jupiter, were also struck. When that happened, those asteroids would shatter into smaller pieces. Events like these can spawn several dozen smaller space rocks; naturally, many resulting bits hailing from the same original object have some things in common like moving around on similar orbits. Astronomers call such groups of asteroids "families."🪨💧 - - - #earth #Space #spaceze #nasa #spaceship #spacex #spacestation #universe #astronomy #astronaut #stars #spaceshuttle #explore

Celebrating World Asteroid Day ☄️ Asteroid Day is an annual global event which is held on June 30, the anniversary of the Tunguska event. Tunguska event (occasionally also called the Tunguska incident) was a large explosion of between 3 and 50 megatons that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia, on the morning of 30 June 1908. The explosion over the sparsely populated East Siberian taiga flattened an estimated 80 million trees over an area of 2,150 km² (830 sq mi) of forest. The Tunguska event is the largest impact event on Earth in recorded history, though much larger impacts occurred in prehistoric times. An explosion of this magnitude would be capable of destroying a large metropolitan area. The United Nations officially declared World Asteroid Day in 2016 to raise awareness about the potential hazards of asteroid ☄️ impacts and to inform them about the crisis communication actions to be taken at the global level in case of a credible near-Earth 🌍 object threat. #asteroidday #worldasteroidday #asteroids #asteroid #meteor #tunguska #Tunguskaevent #dinosaurs #space #astronomy #telescope #cretaceousperiod #spacescience #science #isro #nasa #earth #awareness #spacefact
