Thursday, December 27th 2012. | Universe

Sun is the largest object in our solar system in diameter (at equator) along 1,392,140 miles. The second sequence is occupied by the planet Jupiter with a diameter of 142,984 miles. In the next order of succession is Saturn (120,536 km), Uranus (51,118 km), and Neptune (49 600 km). Our Earth is ranked 6th in this list with a diameter of 12 756 km, followed by Venus (12 103 km) and Mars (6794 km). The order of the 9th and the 10th was occupied by two natural satellites of each Ganymede, Jupiter’s satellites (5262 km) and Titan, Saturn’s satellites (5150 km). This is 10 interesting solar system facts.



1. BIGGEST NATURAL SATELLITE – Ganymede and Titan is a natural satellite (moon), the largest in our solar system. Next in succession followed by Callisto (Jupiter/4.820 miles) and Io (Jupiter/3.632 miles). Months we ranked fifth with a diameter of 3475 km. Meanwhile, Europe (Jupiter/3.126 miles), Triton (Neptune’s/2750 miles), and Titania (Uranus/1.580 miles) following the next sequence. The list is closed with Rhea (Saturn’s/1.530 miles) and Oberon (Uranus/1.516 miles) respectively at number 9 and 10.

2. Anomaly VENUS – Venus rotates on its axis in such a slow, even slower than its orbital period. Consequently there is one year shorter than one day (a day on Venus is equivalent to 243 Earth days, while one year the equivalent of Venus 225 Earth days). Besides, Venus is known to rotate from east to west, opposite of the other planets in our solar system that rotates from west to east, because that on Venus the sun rises from the west and sets in the east.

3. SATELLITE NATURAL – Among all of the planets in the solar system, only Earth have natural satellite. Meanwhile, two of the nine planets of our solar system did not have a satellite, namely Mercury and Venus. The outer planets in our solar system are generally rich in natural satellites. Up to now, has found dozens of natural satellites that circle the planet Jupiter, Saturn and Uranus. Not all natural satellites round, typical of a planet. The second satellite of Mars, Phobos and Deimos as well as small satellites that encircle Jupiter, Saturn, Uranus, and Neptune are known to have an irregular shape

4. MOST TEMPERATURE EXTREMES – Planet with the most extreme temperatures in our solar system is Mercury. Daytime temperatures there reached up to 427 º C, hot enough to melt the metal zinc. At night, temperatures down to -183 º C, cold enough to freeze the krypton. In addition Mercury listed as a planet that is located closest to the Sun



5. Hottest planet – Although Mercury is the planet nearest the sun, but the record as the hottest planet Venus is precisely held by the temperature reaches 482 ° C. It is suspected due to the effect of “greenhouse” of Venus’s atmosphere is rich in elements of Carbon Dioxide

6. Most shining Planet – If Jupiter and the Earth seen from the same distance, then Jupiter would look 164 times more luminous. Viewed from Earth, the most brilliant planet is Venus with magnitude -4.4.

7. NEAREST STARS – the nearest star from Earth is Proxima Centauri. Stars 4.23 light years as far as this are too dim to be seen with the naked eye. Closest star visible to the naked eye is Alpha Centauri (4.4 light years) is seen as the brightest star in the constellation Centaurus in the southern hemisphere sky

8. STARS youngest – two protostar (potential star) known as IRAS-4 in the NGC 1333 Nebula, 1,100 light years from Earth is the youngest star known by humans. Both had to achieve the stable phase as a star in at least the next 100,000 years.

9. STARS of the oldest – 70 stars were found by a team of astronomers led by Timothy Beers (United States) believed to be the oldest stars in the Milky Way. These stars are thought to have formed at about 1 billion years after the big bang (big bang that started the formation of the universe).



10. Red Planet, Mars has no ozone layer and does not have any protective against ultra violet rays. This makes it uninhabitable by humans. Some of facts above are facts about solar system.
