Universe MCQs

• The Sun is the controlling body of Earth’s solar system.
• Sodium was the first metal identified in the Sun
• Hydrogen accounts for 71% of the Sun’s mass, helium 26.5 percent and all the other known elements. 2.5%.
• The Sun’s core lies a giant nuclear furnace which converts hydrogen to helium at a rate of 600 million tonnes per second.
• The diameter of the whole solar system is about 1170 crore kilometers.
• The Sun is made up of extremely hot gases. Its glowing surface is called the photo sphere
• The visible white light of the Sun is made up of 7 colours
• Like other stars, the Sun is composed mainly of hydrogen.
• The Moon is the one and only one satellite of the Earth. It is a natural satellite and is nearest neighbour in space.
• The Moon revolves around the earth while rotating on its own axis. Only 59% of its surface is directly visible from the earth.
• The moon is about 1/4 the size of its mother planet, the earth. It takes 1.3 seconds for Moonlight to reach the earth.
• The sunlight takes about 8 minutes and 16.6 seconds to reach the earth.
• The Moon is the first member of our solar system to have been visited by man.
• The earth rotates around its axis. This axis is an imaginary line passing through the centre of the earth.
• The earth completes one rotation in 24 hours (23 hrs 56 min. 4.09 secs). The earth rotates from west to east.
• The Science which deals with the nature and motion of celestial bodies is called Astronomy.
• Galaxies are dotted like islands throughout the universe. A galaxy is a huge concentration of stars which are held together by the force of the gravity. They are so big that sometimes they are called Island Galaxies.
• Milky Way is our Home galaxy in one of a cluster of 25 galaxies called local group.
• Cosmology is a branch of astronomy that deals with the origin and evolution of the universe.
• In the universe, some matter appears small but emit more energy than the other stars of the milky way. Such stars are called “Quasars.”
• When the hydrogen of a star is depleted, its outer regions swell and redden. This stage of a star is called a “Red Giant”. The sun will turn into a Red Giant in 5 billion Years.
• Black hole stage of the star occurs when the ancient star collapses. Gravity becomes so intense in the hole that nothing escapes even light. This Dark object is thus called a “Black hole”.
• An Earthquake is a vibration or oscillation of the surface of the earth caused by a transient disturbance of the elastic or gravitational equilibrium of the rocks at or beneath the surface.
• Asteroids are a series of very small planets or fragments of planets lying between the orbits of Mars and Jupiter. Ceres (length 1000 km.) is the largest asteroid. Asteroids are also called planetoids.
• It was believed that comets were formed from the remaining material that was left during the formation of the outer planets. A comet consists of three parts i.e. centre, coma and tail.
• The Meteors are probably the remains of comets which are scattered in the interplanetary space of the solar system. On contact with earth’s atmosphere they burn due to friction. Those which completely burn out into ash are called Meteors or shooting star.
• Equinox is the dates when the nights and days are equal. During these days the Sun shines directly over the equator. March 21 is called Unreal equinox and September 23 is called autumnal equinox.
• The moon is said to be in eclipse when the earth comes between the moon and the sun, this is called Lunar Eclipse. Lunar eclipse occurs only on a pull, moon day.
• The sun is said to be in eclipse when the moon comes between the sun and the earth. This is called solar eclipse. A solar eclipse occurs on a new moon day, when the moon is in line with the sun.
