Sun(The king of Solar sytem)

The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest).

It is often said that the Sun is an "ordinary" star. That's true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun.

Curiosity Lander (rover)

Curiosity (rover)

curiosity is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA's Mars Science Laboratory mission

Curiosity transformed from its stowed flight configuration to a landing configuration while the MSL spacecraft simultaneously lowered it beneath the spacecraft descent stage with a 20 m (66 ft) tether from the "sky crane" system to a soft landing—wheels down—on the surface of Mars. After the rover touched down it waited 2 seconds to confirm that it was on solid ground then fired several pyros (small explosive devices) activating cable cutters on the bridle to free itself from the spacecraft descent stage. The descent stage then flew away to a crash landing, and the rover prepared itself to begin the science portion of the mission

Agni 5 Range comparsion

India conducted their first ICBM test launch in April 2012. The Indian Defense Minister described the launch as an “immaculate success.” With the Agni 5, India joins the U.S., Russia, France and China as the only nations possessing this capability

The Agni 5 specifications are still vague, but generally the missile is believed to be a three-stage version of the Agni 3, with an enhanced range of 5000 to 8000 km. A missile with this range is expected to have a launch weight of 50,000 to 55,000 kg, a length of 17.5 to 20 m, and a diameter of 2.0 to 2.2 m. The Agni 5 is also presumed to have up to three MIRV warheads, including countermeasures.
