Astronomers revealed that a comet famously landed on Earth by the European Space Agency Rosetta missions has now made its closest approach to Earth.
Comet 67P was located within 39 Million Miles of Earth on Friday. This is the closest that the space rock has been to Earth since 1969 when it was discovered. It will also be the closest for 200 years.
Also known as Churyumov–Gerasimenko, it is a Jupiter-family comet, originally from the Kuiper belt, orbiting the sun every 6.45 Earth years.
Rubber Ducky was a name given to the duck-shaped, approximately 2.6 mile wide, comet by Rosetta. They oversaw visits by an orbiter in 2014 and a lander in 2015.
Rosetta and Philae, its companion lander, were the first missions to touch down on the surface a comet’s surface. They also sent valuable information back to Earth regarding these orbital iceballs.
The European Space Agency Rosetta mission, which landed on the surface of the comet in 1999, made it famous. It has now made its closest approach to Earth.
Comet 67P passed within 39 million miles (roughly 160 times farther than the moon) of Earth on Friday. This was the closest that the space rock had come to Earth in the past 200 years, as well as the first time it has been discovered.
According to some astronomers, the orbital path of the famed comet began to diverge now from Earth’s. They predict that it will return in 2214.
Although it may still be possible for you to see the snowball if your telescope is larger, you can still look in the direction Pollux (the brightest star in Gemini), although this will make it difficult to see.
The news broke when ESA’s Rosetta mission, which had been on a 10-year-long journey from Earth to orbit the comet.
Philae was the most popular attraction. It became the first man-made object on the comet to touch down in December 2014.
Among the discoveries made were that the icy comet appears to carry some of the key building blocks of DNA and proteins – the amino acid glycine and the mineral phosphorus.
Analysis of a giant dent made by Philae on the comet’s icy boulders during its ‘second touchdown’ in 2014 provides new insights into the softness of the exposed ice.
Philae bounced when it hit the comet six-years ago. European researchers finally discovered its second touchdown location, which was named “skull-topridge” for its unusual skull-like appearance.
While the landing point for the third and first planes were already identified, it was not known where the second one would be.
Laurence O’Rourke (study author) stated, “This ice is 4.5 billion year old and as soft as foam on your cappuccino. It’s as soft on the beach as any sea foam, and it’s even softer after a snowstorm.”
‘You cannot just hit it with an object and expect it to move or disintegrate – it would be like punching a cloud.
“Skull-top Ridge” was my nickname for the area because of how the boulders that Philae impacted reminded me of skulls.
Rosetta instruments could also be used by Astronomers to detect comets that have their own versions of the Northern Lights.

Rosetta with Philae the lander was the first to reach the surface of a Comet. They sent back valuable data to Earth on these orbital-ice ball ice balls.
Experts from the Southwest Research Institute (SwRI) identified the shimmering phenomenon, which on Earth happens when charged particles from the Sun follow the magnetic field lines to the south and north poles of the Earth.
These aurora are created when atoms of the atmosphere collide with each other and form a glowing curtain of bright colours in the sky. Similar aurora can also be seen on moons and planets.
The coma, which is composed of gas and dust and charged particles from solar winds around Comet 67P caused the phenomenon.
THE EUROPEAN SPACE AGENCY ROSETTA PROBE GETTING A CLOSE LOOK AT COMET 67P
The comet, known as ’67P/Churyumov–Gerasimenko’, or just 67P for short, orbits Jupiter at a rate of once every six-and-a-half years.
Amazing images taken by Rosetta’s space probe just released in a massive archive of over 70,000 photos. They highlight key features of the comet 67P/Churyumov-Gerasimenko
The name of the discovery was given to it by two Soviet astronomers in 1969. It measures approximately 2.7 miles by 2.5 miles (4.3 km by 4.1km) at its widest point.
The comet was the focus of the European Space Agency’s Rosetta mission, launched on 2 March 2004.
Rosetta was dispatched to investigate the comet’s activities and launch a Philae lander probe to its surface.
Rosetta was at 67P in 2014, and crashed into the comet in September 2014.
Scientists continue to uncover new details about the probe’s measurements as they comb through Rosetta’s amazing imagery.
The discovery of aurora around the comet was made possible by solar winds and charged particles interacting with its coma.
