A little asteroid will fly past Earth early Tuesday inside the Earth-moon system. The asteroid 2010 TD54 will have its closest come up to Earth’s surface at an altitude of about 27,960 miles nearly 45,000 kilometers at early morning. At to facilitate the time, the asteroid will be over southeastern Asia in the surrounding area of Singapore. During its flyby, Asteroid 2010 TD54 has zero probability of impacting the Earth.

2010 TD54 is expected to be about 16 to 33 feet wide. Due to its small size, the asteroid would need a telescope of reasonable size to be viewed. A five-meter-sized near-Earth asteroid from the undiscovered of the population of about 30 million would be expected to pass daily within a lunar distance, and one might hit Earth's atmosphere about every two years on average.

Asteroid to Pass Within the Earth-Moon System

Small Asteroid To Fly by Earth Tuesday

If an asteroid of size of 2010 TD54 were to enter into the Earth’s atmosphere, it would be estimated to burn up high in the atmosphere and cause no damage to the Earth’s surface.The distance used on the Near Earth Object page is always the calculated distance from the center of Earth. The distance stated for 2010 TD54 is 52,000 kilometers. To get the distance it will pass from the Earth’s surface you need to subtract the distance from the center to the surface and then it takes to pass the distance at about 45,500 kilometers above the planet.

NASA detects the tracks and characteristics of the asteroids and comets passing close to the Earth using both ground and space-based telescopes. The Near-Earth Object Observations Program, commonly called "Spaceguard,”.
