New Delhi:
Google has designed a doodle on new horizon pluto flyby on its homepage.
Pluto is the largest known object in the Kuiper belt, and the second-most massive known dwarf planet in the Solar System.
It was discovered in 1930 and was considered the ninth planet from the Sun.
On Monday, an unmanned NASA spacecraft plunged into the unidentified, and today will make a close shave past Pluto, allowing scientists to have a close view of the dwarf planet's surface for the first time.
However, there were some anxieties on Monday as the $700 million spacecraft, called New Horizons, flown toward Pluto, the last undiscovered border in the solar system.
Investigator Alan Stern says that there is a chance that spacecraft can be lost in an accident with rubble around Pluto.
The closest approach is set for today at 7:49 am (1149 GMT), when the piano-sized spacecraft shaves by Pluto's surface at a speed of 30,800 miles (49,570 kilometers) per hour.
