Although the one and only Chicxulub Impactor (11-81 kilometres in diameter) that wiped out the dinosaurs some 66 million years ago, hold the record for the biggest ever meteorite to ever hit the earth, it is neither the first nor the last of such visits.

Some were lucky enough to survive the journey into our atmosphere and made the earth their home while some just evaporated creating spectacular shooting stars, and of course, there were others who skim past the earth! Among these alien rocks, there are pretty big ones weighing as much as dozens of grownup elephants! 

And these are the 5 largest, burnished and strangest looking meteorites that were lucky enough to enter the earth, obviously since the Chicxulub impactor. Enjoy!

1. The Willamette Meteorite

The 6th largest meteorite found on earth. Currently, on display at the American Museum of Natural History, this massive rock weighs 15.5 tonnes (15500 Kg) and about 7.8 square metres in size. Made from metallic iron, Willamette is one of the 600 iron-based meteorites ever to be found on earth from a total of 25,000 others. its interaction with rainwater is thought to be the reason behind its big cavities. This is believed to hit the earth a few thousand years ago and was initially found in Oregon, USA. The Clackamas Indians who lived in the area calls the meteorite “Tomanowos” and believes it holds great spiritual value.

2. Mbozi Meteorite

This was discovered in the 1930s in Tanzania and is one of the largest meteorites found on earth. Mbozi weighs an impressive 16 tonnes (16,000 Kg) with a 3-metre length and a 1-metre height. The locals had called it the “kimondo”. Mbozi is categorised as an ungrouped iron meteorite and it did not have a crater where it was situated. A man-made plinth supports the rock after it had been partially excavated in the 1930s. Currently, it is being protected by the Department of Antiquities since 1967.

3. The Bacubirito Meteorite

This is the longest meteorite found on earth which is 4.25 metres long. It was found in 1863 in Sinaloa, Mexico and holds the record for the biggest meteorite in Mexico and the 6th largest in the world. This iron meteorite weighs between 20-22 tonnes.

4. El Chaco Meteorite and the Gancedo Meteorite

They both come from a single meteor shower that fell in the Chaco province in Argentina about 4200 – 4700 years ago. El Chaco (29 tonnes) was discovered in 1969. The other larger piece of meteorite, the Gancedo (31 tonnes/ 30800Kg) was discovered very recently in 2016. Gancedo meteorite is now the third-largest in the world.

This meteor shower left 26 craters in the area and across 1350 square kilometres. This group of iron meteorites found in this area is called, “Campo del Cielo”. Its largest rock is 119 x 91 metres in size! The rocks are estimated to be 4.5 billion years old.

5. The Cape York Meteorite

It is believed that this monster rock landed on earth about 10,000 years ago and is about 4.5 billion years old. As nearly as old as our sun! This massive iron meteorite was discovered from Greenland in 1894. The Inuit that lived in the area had been using this as a source of metal to forge their tools.

“Cape York” is the name given to the original meteorite where this piece of iron (called “Ahnighito”) was broken. Ahnighito and two other smaller parts of the Cape York Meteorite can be seen in display at the American Museum of Natural History. At nearly 31 tonnes (30875Kg), Ahnighito is the heaviest meteorite on display in any museum around the world. Because of its weight, the supports Ahnighito weighs on run deep down to the bedrock under the museum. It is the second-largest meteorite in the world.

6. Hoba Meteorite

This is the monster rock of them all! Weighs a massive 60 tonnes and almost twice as the second-largest space rock Ahnighito. Hoba is the largest intact single-piece meteorite in the world. Even today, it stays where it was landed in Namibia 80,000 years ago. With a flat surface on both sides, Hoba is 2.7×2.7×0.9 metres in size. It has a composition of iron, nickel and cobalt. It was found in 1920 by accident while Jacobus Hermanus Brits was ploughing the field above it. Hoba does not have any crater where it landed.

Here are those most advanced, creative and enigmatic microbots that you never knew existed and would make life so much easier for us. Enjoy!

1. Lego-Like Magnetic Microbots That Make Neural Networks Work (2020)

Scientists from South Korea developed this state of the art microbots, which can fuse (just like lego pieces) individual neurons together making neural networks that work. Paving the way to reverse neural diseases like Alzheimer’s, this microbot is only 300 micrometres long and 95 micrometres wide. This is definitely something to look forward to!

2. Microscopic Robot With Limbs That Move (2020)

You may have seen it. This minuscular bot made such a buzz in the scientific world when it first came out. So tiny, even a microscopic single-cell paramecium looks gigantic that swims around it! Standard electronic signals control their semiconductor components allowing them to ‘walk’. And what’s more, these fascinating creatures could be easily mass-produced, have the potential to be built with AI and one day could definitely be crawling in our veins and tissue, finding, fixing or delivering things!

3. Shapeshifting Swarm Of Microbots (2019)

These mass-produced, single ‘species’ microbots can carry out various tasks by shapeshifting collectively into different forms (chains, ribbons, vortexes, etc.). They can tumble, roll, spin and oscillate in movements. Their multitasking ability has given the researchers hope to one day effectively utilise them in biomedical treatments and various in vivo diagnostic procedures.

Although ‘Microbot’ (micro + robot) means a robot about a millimetre or less in size, these amazing inventions could also be called “microbots” because they are tiny and just as awesome!

4. Robeetle (2020)

Weighed less than 1/100th of a gram, this tiny robotic beetle has artificial ‘muscles’. It does not use any batteries and powered only by methanol. Made to look like the Tiger beetle (Cicindela eburneola), Robeetle can crawl, climb up on ramps and could carry things weighing 2.6 times more than its body weight. It is one of the lightest and smallest autonomous robots ever to be built. Robeetle’s journey would cover environments that are inaccessible for humans. What a pretty little thing!

5. Self-organising Kilobots (2014)

Harvard scientists created these Kilobots that can assemble into large or complex shapes autonomously. This is a form of collective artificial intelligence that mimics biological collectiveness of beings such as a colony of army ants forming into structures which can be used as bridges or rafts to move them to safety. Imagine what could these Kilobots achieve in the future! Swarms of these tiny robots could work as one unit in rapid disaster responding, environmental cleanups or simply built into self-driving vehicles.

6. Jellyfish-Inspired Tiny Soft Robot (2019)

This cool gadget mimics the exact motion and the body of the Ephyra jellyfish. It can swim faster in different ways and can pulsate which allows them to carry ‘food’ just like the jellyfish.

7. The RoboBee (2019)

This latest version of the centimetre sized RoboBee is a stepping stone for a miniature robotic drone. Weighing just half of a paperclip this robotic bee design has an untethered flying mechanism. Powered by inbuilt solar panels, RoboBee can flap its wings 120 times per second. And for sure these types of robots are going places!

Some lesser-known cool tiny bots in the last decade.

• The Micro doctors
• Flying Fish Robot
• Microbots that can swim with their elastic tail
• Self-propelling DEAnsect

A Final Thought

For all those who became a tad worried about this tiny robotic invasion into our bodies, our lives, let me share with you a very interesting futuristic view that was written by Bruce Sterling in his 1998 futuristic science fiction, ‘Distraction’. In his book, people from the future wield a fancy handheld device that can do ‘wonders’ like giving superfast accurate directions, storing phone numbers and giving fast access to them and many more, all with our voice command. Sounds a lot like a smartphone, doesn’t it? Something that sounds too fantastic or too futuristic to be true might firmly be in our reality soon. Well, I am hopeful!

Have a good day!
