An asteroid named 2021 GW4 about the size of a small truck flew harmlessly past Earth on April 12.

This recently detected space rock was travelling at 18,706 miles per hour (30,104 km/h) or 8.36 kilometres per second, relative to Earth.

According to reports, the rock was well inside the ring where many artificial satellites orbit around the Earth at an altitude of 35,786 km.

The asteroid was about 26,200 km away from Earth — less than one-tenth the distance between the Earth and the moon, and quite close as far as asteroid approaches go. The average distance between the Earth and the moon is about 384,400 km.

Asteroid 2021 GW4 was discovered on April 8, 2021, using the 59 inches (1.5 metres) telescope of the Catalina Sky Survey at Mt. Lemmon, Arizona.

According to NASA's Center for Near-Earth Object Studies, more than 500 asteroids have been already identified this year.

A mini truck-sized asteroid just gave Earth a close shave

School students in India have discovered 18 asteroids&nbsp;as part of a global science programme, according to the&nbsp;International Astronomical Union (IAU), an organisation that assigns official names and designations to celestial bodies.

The International Asteroid Discovery Project was conducted by STEM and Space, an organisation working towards the learning of astronomy and space science in India, along with the International Astronomical Search Collaboration (IASC) as part of a NASA citizen science project.

Over the last two years, 150 students from all around India participated in this two-month-long campaign to find asteroids, making this the largest asteroid discovery project in India, Mila Mitra, Co-founder and Academic Head of STEM and Space said.

In the project, the students from India, and across the globe analysed the high-quality astronomical data provided by IASC, an online scientific program for kids to discover Asteroids and Near-Earth Objects (NEO).

NEOs are rocky objects in an orbit between Mars and Jupiter, which pose a challenge to Earth as they may get perturbed out of their orbit and pose a threat of impact. 
According to Mitra and her team, NASA has initiated programs like IASC to track such asteroids regularly, also open to citizen scientists and students to enable the discovery and tracking of more asteroids.

She explained that in the project the students use advanced software analysis, "spending nearly two-three hours each day" to look for asteroids and report their findings. 
Of the 372 preliminary asteroids flagged by the students, 18 were finally declared to be "provisional" or confirmed discoveries of asteroids, Mitra noted.

"IAU confirmed these findings last month," the STEM and Space co-founder added.

Mitra believes brings such programs can bring the experiential learning of science, technology, engineering and medicine, or STEM, via the domain of space with a gamut of hands-on learning workshops.

However, she said more efforts need to be taken to extend the reach of such programs to government-run schools and those in rural parts of the country to make the citizen science projects more equitable.

Mitra noted that all the discoverers received Provisional Discovery Certificates from IASC and NASA for their scientific contribution in discovering asteroids.
