No, the inner most layer of the earth is called inner core. The Earth's inner core is made up of iron and nickel. It has trapped gases and hot liquids under great pressure. Sometimes these gases burst out and explode outside the crust as volcanoes.

The Solar System includes sun, planets, stars, and other heavenly bodies. This is an odd option as rest all options are the types of constellation.

Kalpana Chawla was born in Karnal, India. She was the first Indian American astronaut and first Indian woman in space. In 2003, Chawla was one of seven crew members killed in the Space Shuttle.

Earth is positioned third from the Sun. This planet appears blue in colour due to presence of water on it. This is the only planet in the solar system which supports life on it, and has all conditions which supports life on it.  This is making it odd from other options.

Earth takes 365 rotations on its axis when it moves around the Sun once. Earth completes its one revolution around the sun in 365 days, i.e,  a Year. It takes 23 hours, 59 minutes and 4 seconds for the Earth to make one complete rotation on its axis.

This is right answer, planet Venus is Earth's neighbor, Mars is called red planet due to presence of iron oxide on its surface. Jupiter is giant gas because it is a giant ball of gas. Uranus is greenish blue in colour, as it gets its blue-green color from methane gas in the atmosphere.

This is a correct answer. Neil Armstrong was the first man who landed on the moon. First animal on moon was Laika. She was a stray dog launched by the Soviet Union in 1957. The first person who walk in space was Alexei Leonov.  He was the first person to conduct a spacewalk on March 18, 1965. Valentina Tereshkova was the first woman to go into space, she flew Vostok 6 in 1963, spending almost three days in space.

Yes, some planets have their own natural satellites. A natural satellite or moon is a celestial body that orbits a planet. Like earth has a natural satellite the moon.

Although the Sun appear larger than any other star, there are many stars which are much larger. The Sun sppears so large campared to other starts because it is so much closer to us than any  other star. The Sun is an average size star. So this is a right answer.

No, the purpose of an ordinary telescope is to make objects that are far away from you appear closer, so you can see them better. Telescopes are used mostly to explore our solar system. So this is the wrong statement.

A Comet is a small solar system body that orbits the Sun. When these Comets come close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail.

This is the correct answer. Sirius is the brightest star in sky in our galaxy. The Milky Way is the galaxy that contains our Solar System. Volcano erupts lava, which is the molten rock expelled by a volcano during an eruption and a shooting star is another name for a meteoroid that burns up as it passes through the Earth's atmosphere.

No, stars are very far from the Earth that is why they appear very small in size,  from the earth.

Mercury is the nearest planet from the Sun, so this is the wrong statement.
