Answers:
1. – Sun. The Sun, which is at a distance of 92,955,900 miles from Earth is the nearest star to Earth. The distance of the Sun from the Earth is termed as 1 Astronomical Unit. Light from the Sun takes nearly 8 minutes to reach the Earth.
2. – Proxima Centauri. Proxima Centauri, which was discovered in the year 1915, is at a distance of nearly 4.2 light years from Earth. One light year is equal to the distance light travels in one year.
3. – Dog Star (Sirius). Sirius A (Alpha Canis Majoris), also known as the Dog Star, is the brightest star visible from the surface of Earth. It has an apparent brightness magnitude of -1.46. It is nearly 8.65 light years away from the Earth and has luminosity 26 times greater than that of the Sun. It is visible in the winter months of the northern hemisphere.
4. – Jupiter. Jupiter, with an equatorial diameter of 88,080 miles is the largest of the nine planets that revolve around the Sun. Its mass is approximately 320 times, and volume 1300 times that of the Earth. In other words, Jupiter could contain 1300 Earths.
5 – Pluto. Contrary to popular opinion, Mercury is not the smallest planet. Pluto, the outermost planet, with a diameter of 1430 miles is the smallest planet of our solar system.
6 – Pluto. Pluto, discovered by William Tombaugh, is the planet which is farthest from the Sun. It is the coldest planet of the solar system. It is so cold that when in 1992, scientists discovered nitrogen on Pluto, it was in SOLID form. It is the only outer planet made of solid material.
7 – Mercury, at a speed of 107,030 mph, takes about 88 days to orbit the Sun and is the fastest planet of our solar system.
8 – Venus. American and Russian space probes have found out the temperature on the surface of Venus is 465 oC, making it the hottest planet of our solar system.
9 – Venus. Venus is at times about 25 million miles away from the Earth. Mars is at a distance of 34 million miles.
10 – Venus. Venus, also known as the Evening star, is the brightest planet as seen from the surface of the Earth. It has an apparent brightness magnitude of -4.4.
11 – Earth. Our planet Earth, with a density of nearly 5.5 times that of water, is the densest planet of our solar system. Saturn, with a density about 0.69 times that of water, is the one with the lowest density. If the planets were placed in a huge ocean, then Saturn would be the only one to float on the water.
12 – Ganymede. Ganymede, the satellite of Jupiter, with a diameter of 3275 miles is the largest satellite of our solar system.
13 – Ganymede. Ganymede is one of the 16 satellites of Jupiter. It has a mass nearly double that of the moon.
14 – Phobos. Phobos is one of the 2 satellites of Mars. It is at a distance of nearly 5800 miles from the center of Mars making it the satellite that is closest to the parent planet.
15 – Sinope. Sinope is the outermost of the 16 satellites of Jupiter. It is at a staggering distance of 14 million miles from Jupiter.
16 – Pacific Ocean
Pacific Ocean represents nearly half of all the world’s oceans. Oceans represent 94% of the Earth’s water.
