If the Earth is the size of a marble of diameter 1 cm then, the biggest planet, Jupiter would be the size of a coconut of diameter around 11 cm. Gather all this material and arrange it in correct order.</li>\r\n\t<li><b>Mapping the distances: </b>Did you put the above objects in line? Surely, they are not as close as you must have put on a large table. How spread out are they? Let us find out. Go on the school playground, a long corridor or on a quiet road. We need at least 120 meter space in one direction.</li>\r\n\t<li>If the Earth is imagined to be of diameter 1 cm, then the Sun would be of diameter 109 cm. Draw a circle of diameter 109 cm on the ground. Imagine that there is a sphere of this diameter here. This is your Sun. (It is difficult to get hold of such a large sphere, so we are drawing a circle and imagining a sphere.)</li>\r\n\t<li>Now measure 453.9 cm from centre of the Sun. Place the small bead of diameter 0.4 cm here. In the shrunken Solar System, this is where the tiny (!) Mercury would be!</li>\r\n\t<li>Now, measure another 40 meters (85 meters from the centre of the Sun). Place the marble of Venus there.</li>\r\n\t<li>Measure 32 meter (117 cm from the centre of the Sun). Place the marble of the Earth there.</li>\r\n\t<li>If you have not already run out of space, place Mars, that is the bead of 0.5 cm at 178 meters from the centre of the Sun (61 meters from the Earth).</li>\r\n\t<li>The next planet, Jupiter, which is a coconut in our model, would be at 601 meters from the Sun, that is more than half kilometer. You will need good 10 minutes to walk this distance, So henceforth, only imagine where the rest of the planets are in the shrunken solar system.</li>\r\n\t<li>Saturn, which is an orange in our model, is more than 1 km from the Earth and a 15-minute walk away.</li>\r\n\t<li>Uranus, the table tennis ball, is two-and-a-quarter km, more than a 25-minute walk away. No wonder, it is hardly visible from the Earth.</li>\r\n\t<li>Finally Neptune is at a good three and a half km distance from Earth (about 40 minutes walk)! Imagine how big its orbit would be. Now you know why Neptune takes almost 165 years to complete one revolution around the Sun!</li>\r\n</ol>\r\n\r\n<p><span style=\"font-size:14px;\">Apart from the Sun and the planets, there are other smaller objects in our Solar System. Let us learn &nbsp;more about these objects.</span><br />\r\n<br />\r\n<strong>Satellites: </strong>When an object moves around a planet due to gravitational force between them, it is called a \u2018satellite\u2019 or a \u2018Moon\u2019 of that planet. Apart from Mercury and Venus, all other planets have satellites. The Earth has only one Moon, and Mars has two satellites. So far, we have found 67 satellites of Jupiter. Four of these are big: Ganymede is bigger than Mercury, Io and Callisto are bigger than our Moon, and Europa is slightly smaller than our Moon. Galileo Galilei was the first one to see them when he watched Jupiter through a telescope in 1610 (hence they are called the Galilean Moons). He identified them as the satellites of Jupiter. This was the first time when we learned that other planets also have satellites.<br />\r\n<br />\r\nSaturn is known to have 62 satellites (only one of them is as big as the Moon). Uranus has at least 27 satellites, and Neptune has 14. Imagine the sight of multiple Moons being visible at a time from these planets! Refer to <strong>Figure 1</strong> for selected Moons in the solar system.</p>\r\n\r\n<p style=\"text-align: center;\"><img alt=\"U3L2_Fig1\" src=\"/media/1/2/7/25f2d94aeb4e055ea3e81dc056c7e18bc8b8a74359c68e3b2e4297ad6ff64.png\" style=\"border-width: 2px; border-style: solid; width: 500px;\" /></p>\r\n\r\n<p style=\"text-align: center;\"><br />\r\n<b><span style=\"font-size:14px;\">Figure 1: Sizes of selected satellites in the solar system as compared to the Earth</span></b><br />\r\n&nbsp;</p>\r\n\r\n<p><span style=\"font-size:12px;\">Credit: By Originally uploaded from NASA by Bricktop; edited by Deuar, KFP, TotoBaggins - solarsystem.nasa.gov, Public Domain, <a href=\"https://commons.wikimedia.org/w/index.php?curid=1641353\" target=\"_blank\">https://commons.wikimedia.org/w/index.php?curid=1641353</a></span></p>\r\n\r\n<p><br />\r\n<span style=\"font-size:14px;\"><strong>Artificial Satellites: </strong>When human beings launch objects into the orbit of any planet, they are known as artificial satellites. The Earth has many artificial satellites revolving around it. Artificial satellites are useful in weather forecasting, in Tele and Radio communication and GPS (global positioning system), which is used in mobiles to determine our position. The Indian Space Research Organization (ISRO) &nbsp;has been successfully launching satellites since 1975. A rocket is needed to carry the artificial satellite into its orbit and launch it. We have launched many artificial satellites using our own rockets from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. Among them, a satellite named Astrosat was launched on September 28, 2015 to carry out research in astronomy (<strong>Figure 4 a</strong>). Artificial satellites have been launched to revolve around other planets as well. Mangalyaan (Mars Orbiter Mission) is one such satellite launched by ISRO on 5 November 2013.</span></p>\r\n<br />\r\n<br />\r\n&nbsp;",
