Do you know what are Jovian planets? Here’s our Solar System quiz for you 

The sun and everything that orbits it, including planets, moons, asteroids, comets, and meteoroids, make up the solar system. Since the sun’s name, ‘Sol’, has been derived from ‘solis’, the Latin equivalent for sun, we call it the solar system. The solar system comprises of eight planets which have their own characteristics and placement within the universe. Do you think you know all about the solar system?

ANSWERS 

Q1. (a) 

Humans can see the photosphere portion of the Sun. It is the Sun's deepest layer that we can see directly. The photosphere has a temperature of roughly 10,000 degrees Fahrenheit. This layer, which resembles a dazzling disc, is responsible for sending light and heat to Earth. 

Q2. (c) 

During a total solar eclipse, the sun’s outermost layer called corona, is visible to us. Except during a total solar eclipse, it cannot be viewed with the naked human eye. 

Q3. (c) 

In terms of size, Jupiter is the largest planet in the solar system.  It is also said to be the fifth planet from the sun. Jupiter's stripes and swirls are actually cold similar to windy clouds of ammonia and water floating in an atmosphere of hydrogen and helium. 

Q4. 

Jupiter, Saturn, Uranus, and Neptune are the four Jovian planets in the solar system. A Jovian planet is a gas giant that is mostly made of hydrogen and helium gas with various degrees of heavier components. 

Q5. (a) 

The planet earth with 5.514 gram per cubic centimetre has the highest density in the solar system. This is because earth has no gaseous components and its entire mass is concentrated and compressed. This reduces the planet's volume while increasing its density. 

Q6. (c) 

Mercury, being the closest to the sun, has the shortest revolution period around it. In other words, it takes Mercury only 88 days to complete its orbit around the sun. 
Q7. (c) 

The solar system orbits the centre of the Milky Way, a large, spiral-shaped galaxy at about 5, 15,000 mph (828,000 kph). It is named so due to its appearance as a soft glowing light made up of billions of stars. 

Q8. (b) 

Pluto is located beyond Neptune in the Kuiper belt. It has five moons and no rings. Pluto was once regarded as a planet, but the International Astronomical Union, since 2006 considers it a dwarf planet. 

Q9. (b) 

Venus glows so brightly that it is the first ‘star’ to appear after the sun sets, and the last to disappear before the sun rises. Hence, the names ‘Morning Star’ and ‘Evening Star’ have been assigned to it. In fact, the ancient Greeks and Egyptians considered Venus to be two distinct objects.
