June 30 is Asteroid Day! https://asteroidday.org/

In honour of the occasion, here is a list of recent & upcoming Earth-asteroid encounters featuring potentially hazardous near-Earth asteroids (NEAs) that we *really* need to keep an eye on. We don’t want to end up like the dinosaurs!

Sorry about the Starlink trails, by the way.

Who can forget the NASA DART mission, when the spacecraft rammed into asteroid Didymos's moonlet Dimorphos on Sep 26, 2022, to demonstrate the kinetic impactor technique to change the trajectory of an asteroid.
The impact shortened Dimorphos's orbital period of 11 hour and 55-minute by 33 minutes.

Samples recovered from near-Earth asteroid #Ryugu represent chemically the most primitive and pristine #SolarSystem materials yet analyzed in a laboratory, a 2022 Science study suggests. https://scim.ag/3bX #AsteroidDay #press

Apparently today is #asteroidday so a little shameless plug for this old Asteroids spin I made back in 2020: https://chaslinux.itch.io/fasteroids

It's Asteroid Day!

It is held on June 30 each year to mark the date of Earth’s largest asteroid impact in recorded history, the Siberia Tunguska event.

Asteroid Day was co-founded by astrophysicist and musician Dr. Brian May of the rock group Queen, Apollo 9 astronaut Rusty Schweickart, filmmaker Grig Richters, and B612 President Danica Remy to educate the public about the importance of asteroids in our history and the role they play in the solar system.

By comparison, 433 Eros, the 2nd-largest near-Earth object, has an ominous shape and a volume-equivalent diameter of a 16.8 km.

Eros is a Mars-crosser asteroid. Dynamical integrations suggest that Eros may evolve into an Earth-crosser within as short an interval as 2 million years, and has a roughly 50% chance of doing so over a time scale of 100-1000 million years.

The largest NEO is 1036 Ganymed at 35 km diameter.

As of today and according to statistics maintained by CNEOS, 32,268 near-Earth asteroids (NEAs) have been discovered. ranging in size from 1 meter up to 32 km. The number of near-Earth asteroids over 1 km in diameter is estimated to be about 853, of which over 90% have been discovered. 2,304 of the NEAs are classified as potentially hazardous asteroids (PHAs).

Luckily this is a sparsely populated area of Siberian taiga, but it’s estimated that 80 million trees were flattened.

Fun fact: Asteroid Day was co-founded by astrophysicist/rock musician Dr Brian May of Queen.

Happy International Asteroid Day! Today, we celebrate the scientific achievements and collective efforts to protect our planet from potential asteroid impacts. By raising awareness, fostering innovation, and strengthening international cooperation, we can advance planetary defense and ensure the safeguard our home, Earth. #AsteroidDay #PlanetaryProtection #ScientificAdvancement

Happy #asteroidday , I guess. https://asteroidday.org/

🪷 30 June is #AsteroidDay. We honor dwarf planet #Antinous, a Near-Earth #Asteroid. It's one of the #Apollo #Asteroids named for Classical deities. It passed by Earth in 1992, 1999 and will be back later this century. And it could visit us with a bang: antinousstars.blogspot.com/2022/06/antino…https://antinousstars.blogspot.com/2023/06/antinous-asteroid-is-neighbor-who-could.html 🪷

Hoy celebramos el día del Asteroide. Recordando el impacto sobre Tunguska tal día como hoy en 1908 y montando un taller de #cienciaciudadana en el Planetario de Pamplona. #AsteroidDay

What an evening last Friday at our Apocalyptic Wine Tasting 🤩 Exciting wines & exciting talks! Thanks to everybody who joined and especially to our speakers Michael, Emily & Richard @zinken If you could not make it: on #AsteroidDay June 30th we will be having another tasting with meteorite wine ☄️ at the Karlstorkino. Mark your calendars.

Zum Thema #Meteor und #Asteroid gibt es am 30.06.2023, dem Asteroid Day 2023, im #Astronomiemuseum eine #Veranstaltung für #Kinder, bei der wir vielleicht auch echte Meteorite finden werden?
