A newfound asteroid will buzz close by Earth today, flying safely between our planet and the orbit of the moon.

The asteroid 2014 DX110 will zip by Earth at 11am AEST (2100 GMT) today, just days after its discovery on February 28. NASA officials say it poses no threat to the Earth.

"This asteroid, 2014 DX110, is estimated to be about 100 feet (30 metres) across," officials at NASA's Jet Propulsion Laboratory in California wrote in an alert.

"Its closest approach to Earth will be at about 217,000 miles (about 350,000 kilometres) from Earth at about 1 p.m. PST (11am AEST) on March 5. The average distance between Earth and its moon is about 239,000 miles (385,000 kilometres)."

This image shows the relative locations of asteroid 2014 DX110 and Earth on March 4, 2014. The asteroid will make its closest approach to Earth on March around 11am AEDT today.

Two web-based skywatching services, the online Slooh observatory and the Virtual Telescope Project in Italy, will attempt to offer free live views of asteroid 2014 DX110 during its flyby. You can watch both asteroid flyby webcasts on Space.com here, beginning at 10:30am AEDT. The webcasts are heavily dependent on weather conditions at the observing sites.

The first asteroid 2014 DX110 webcast at 10:30am AEDT comes courtesy of the Virtual Telescope Project overseen by astrophysicist Gianluca Masi in Ceccano, Italy. The webcast will cover the incoming asteroid's approach and closest flyby to Earth during today's space rock encounter.

Masi observed the asteroid Tuesday night by telescope, snapping a photo that revealed the asteroid to be a white pinprick of light in a sea of black space. You can follow Masi's webcast directly at the Virtual Telescope Project website here.

At 11am AEDT (2100 GMT), the Slooh observatory will webcast its own coverage of asteroid 2014 DX110 using the company's remote-controlled telescopes. Slooh's Paul Cox will host the observing event.

Slooh officials said it will be a challenge to see asteroid 2014 DX110 because, "with its small size, location, and incredible rate of motion, there is a high probability we will not capture the asteroid during the broadcast.

Asteroid 2014 DX110 was discovered last week by astronomers using the space rock-hunting Pan-STARRS 1 telescope in Haleakala, Hawaii. The telescope is one of many around the world used to seek out and track near-Earth objects. NASA's Near-Earth Objects program at the Jet Propulsion Laboratory in Pasadena, California, oversees one of those efforts.

"NASA detects, tracks and characterises asteroids and comets using both ground- and space-based telescopes," JPL officials said in a statement.

"The Near-Earth Object Observations Program, commonly called 'Spaceguard,' discovers these objects, characterises a subset of them and identifies their close approaches to determine if any could be potentially hazardous to our planet."
