Planets Planets: The planet count in our solar system has gone as high as 15 before new discoveries prompted a fine tuning of the definition of a planet. The most recent change was in 2006 when scientists reclassified Pluto as a new kind of object - a dwarf planet. Dwarf Planets: This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system. There could be hundreds more of these small worlds far out there waiting to be discovered.
Planetary Transits Page Transit of Mercury on 1973 Nov 10. The transit or passage of a planet across the disk of the Sun may be thought of as a special kind of eclipse. As seen from Earth, only transits of the inner planets Mercury and Venus are possible. Planetary transits are far more rare than eclipses of the Sun by the Moon. The Universe within 50000 Light Years - The Milky Way Galaxy About the Map This map shows the full extent of the Milky Way galaxy - a spiral galaxy of at least two hundred billion stars. Our Sun is buried deep within the Orion Arm about 26 000 light years from the centre. Timeline of the universe Using observatories on the earth and in space, astronomers have been able to study the nature of the cosmos in unprecedented detail. By analysing the motion of distant galaxies, they have discovered that the whole cosmos is expanding under the influence of forces unleashed at its birth in the big bang. Combined with studies of the radiation left over from that primordial explosion, they have found that the universe was born 13.7bn years ago, give or take 200m years. Pinning down the date of creation with such precision is impressive, but scientists have gone much further.
Scientist Claims Our Solar System Evicted A Planet So Earth Could Survive Colorado scientist David Nesvorny was running solar system evolutionary simulations recently when he realized that during 6,000 different simulations the Earth couldn’t survive during the system’s early years based on the current planetary count. Once Nesvorny added another planet to the system however Earth survived as expected. According to his work our solar system at one point had a ninth planet, a gas giant that was nudged out of the system billions of years ago to make room for Earth’s survival. According to the Mother Nature Network “gas giant number five” started off bound together with Saturn and Jupiter and pushed out lighter planets including Neptune and Uranus eventually to be pushed out of the system on its own after a collision with Jupiter.
Our Solar System Our planetary system is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. Beyond our own solar system, we have discovered thousands of planetary systems orbiting other stars in the Milky Way. Go farther. Explore Our Solar System in Depth › 10 Things to Know About Our Solar System Behold: The Māori solar system! – joe rojas-burke Traditional stargazers in New Zealand referred to celestial bodies as Te Whānau Mārama, or the family of light. They observed, without telescopes, most of the planets in our solar system and gave them beautiful names that vary from mythic and imaginative to strikingly descriptive: Mercury is Whiro, a mythic being representing darkness and evilVenus is Kōpū, or Kōpū Tāwera, the morning star. When it rises in the evening it is called Meremere, or Meremere-tū-ahiahi.Earth is Papatuanuku, mother of all living things.Earth’s moon is Te Marama, offspring of Tangotango, the blackness of the heavenly night, and Wainui, the ocean – the two cosmic entities that also birthed Te Ra, the sun, and other stars.Mars is Matawhero, I believe a reference to the planet’s red face.Jupiter is Kopu-nui, translated by some as ‘giant belly’ and indicating an understanding of this planet’s great size.

Claudius Ptolemy circa 150 AD Nineteen hundred years ago the Greco-Roman astronomer, Claudius Ptolemy, left us an enigma. We’ll have a Blue Moon this weekend Next Blue Moon August 21-22, 2021 Our last Blue Moon came on the night of Halloween, 2020. That night, the Blue Moon was near red Mars. But that full moon – like most Blue Moons – was blue in name only. We called it a Blue Moon because it was the second of two full moons in a calendar month.
What color is the universe? When you look up at the night sky, it's easy to think that the universe is a never-ending sea of blackness. But if you measured the visible light from all of the luminous celestial bodies out there, what would the average color of the universe be? Let's get this out of the way first: It's not black.
