Earth’s quiet companion, 2023 FW13, has circled with our planet for decades - yet almost no one knew it existed. Why does a tiny object follow us through space? The answer might surprise you.  Know the mystery behind this hidden quasi-moon.

'Since 60 years': What is Quasi-Moon and why is it silently orbiting Earth?

A team of Indian scientists recently discovered four new near-Earth asteroids during a search training programme overseen by National Aeronautics and Space Administration (NASA).

NASA collaborated with the International Astronomical Search Cooperation and Vigyan Prasar, an organisation within the purview of India’s Ministry of Science and Technology to assist in the discovery. The six-member team of watchdog citizens-turned scientists used communicators and teachers to detect the rocks, setting an industry precedent.

Meet the team: How did they achieve the feat?

The discovery team was led my Meka Susatya Rekha, a science teacher and the recipient of the National Teacher Award, local media reports claimed. Rekha teaches at a school in Rajahmundry, Andhra Pradesh and has received praise by Indian Prime Minister Narendra Modi for her accomplishments in the field of teaching.

According to Deccan Chronicle, other team members include K Kiran Kumar Reddy from Kadapa, M Suresh from Vijayawada, Neelakantaiah from Chittoor. In addition, the team also received help from an organisation which aims to popularise science called Vijnana Bharati whose PVLN Sriram helped with the discovery.

With this discovery, scientists are backing on the team to unearth much more. With this hope, the six-member team is expected to participate in an asteroid campaign set to take place on India’s 75th Independence Day this year.

As part of their programme, the scientists underwent a 45-day long training programme under the wing of Saptarishi India Asteroid Search Campaign, which was overseen by the All India Asteroid Search Programme.

To help with their goals, the scientists used data and images from the Panoramic Survey Telescope and Rapid Response System, a space telescope situated in Hawaii, United States.

But what are near-Earth asteroids?

Essentially frozen rocks, near-Earth asteroids are objects that come in proximity to Earth due to their orbits. Most near-Earth objects are identified as asteroids, but a few are also categorised as comets. There are more than 25,000 known near-Earth asteroids and at least a hundred near-Earth comets.&nbsp;

Scientists use two scales referred to as “Torino” and “Palermo” to ascertain the risk presented by such near-Earth objects. The scales are also used to identify the risks of the objects impacting Earth.&nbsp;

Even if measuring as small as 20 metres, asteroids are capable are wreaking havoc to the local environment and populations. If big enough, asteroids could create a crater on Earth. They’re also capable of setting off tsunamis if they make impact in the ocean.

Any body in the universe is categorised as a near-Earth object if their closest approach to our Sun is less than 1.3 astronomical units, a measure of the distance between the Earth and Sun. All near-Earth objects larger than 140 metres are considered potentially hazardous objects.

Indian scientists discover four near-Earth asteroids in NASA-backed research programme

NASA has warned that a monstrous 220-meter asteroid is headed Earth’s way early in the new year.

Year 2020’s final asteroid, 2020 YB4, measuring just 36 metres in diameter or roughly half the wingspan of a 747, passed by the Earth shortly after 6 am UTC at a distance of 6.1 million kilometres.

Keeping up with the trend, in the first days of January, three additional, small Near Earth Objects (NEOs) will grace the Earth with their presence.&nbsp;

The 15-metre asteroid 2019 YB4 will fly by at a safe distance of 6.4 million kilometres. It will be followed up by two more chunks of cosmic debris in the form of the 15-meter 2020 YA1 and the 21-meter 2020 YP4, which will pass by at 
1.5 and 2.1 million kilometers respectively, the next day.

A bigger asteroid will shoot past Earth on January 3, as the relatively mountainous 2003 AF23, measuring an impressive 220m in diameter or about as wide as the Golden Gate Bridge is tall, at 6.9 million kilometers.
