Pluto has five known moons: Charon, the largest, whose diameter is just over half that of Pluto Styx Nix Kerberos and Hydra. Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km 3.67 billion mi). ![]() Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometers 2.8 to 4.6 billion miles) from the Sun. Pluto has only one sixth the mass of Earth's moon, and one third its volume. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun. Namaste, Congratulations to and India's first interplanetary mission upon achieving Mars orbit.Pluto ( minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. #JourneyToMars /lz90flOZLG- NASA September 24, 2014 ![]() We congratulate for its Mars arrival! joins the missions studying the Red Planet. The United States has expressed interest in cooperating with India as their spacecraft gather data about the planet. India’s Mars Orbiter Mission is in the company of NASA’s two Mars rovers on the ground, a European orbiter and NASA orbiters including the MAVEN, which has been there since Sunday. About half of all spacecraft sent on missions to the planet have veered off course, malfunctioned or crashed. Once nears Mars’ orbit, India’s spacecraft had to execute a series of complicated and critical maneuvers. READ: Is India’s Mars mission the latest escalation in Asia’s space race? Japan’s 1998 attempt with the spacecraft Nozomi was also unsuccessful due to fuel problems. The mission has been freighted with patriotic significance for India since its inception and is seen as a symbolic coup over its rival, China, which is also ramping up its space ambitions.Ĭhina’s joint mission with Russia in 2011, which contained the Chinese Mars satellite Yinhuo-1, stalled and eventually fell back to Earth. What is red, is a planet and is the focus of my orbit? /HDRWjOcPus- ISRO's Mars Orbiter September 24, 2014 The Mars Orbiter kicked off its interplanetary debut with its own Twitter account. Its mission is to orbit the Red Planet, mapping its surface and studying the atmosphere. The spacecraft launched on November 5, and has traveled over 650 million kilometers to enter Mars orbit. The groundbreaking Mars mission wasn’t without controversy – with some critics who said India should spend the money on other issues. Satish, a space expert based in Bangalore. “It shows how optimal is the design, that way we’re able to cut cost and we’re not compromising quality,” said S. ![]() Interactive: Exploring Mars from Viking to MAVEN Some space observers noted that India’s Mars orbiter cost less than the $100 million budget for the space thriller film “Gravity.” With a price tag of $74 million, the Mars Orbiter Mission cost a mere fraction of the $671 million NASA spent on its MAVEN spacecraft, which arrived to Mars earlier this week. But we have prevailed.”Īnd India reached Mars with significantly less money. “Of the 51 missions attempted so far, a mere 21 had succeeded. “The odds were stacked against us,” Modi said.
