Here's the session:
Q: (L) How many planets are in our solar system?
Q: (L) Could you tell us the names of all the planets, their distances from the sun, the chemical composition, and the diameter.
- Mercury=Opatanar, 36 million miles from Sun; 3000 mi. diameter.
- Venus=Pemuntar, 67 million miles from Sun; 7,500 mi. diameter.
- Earth=Saras, 93 million miles from Sun; 7,900 mi. diameter.
- Mars=Masar, 141,500,000 miles from Sun; 4,200 mi. diameter.
- Jupiter=Yontar, 483,400,000 miles from Sun; 88,700 diameter.
- Saturn=Zendar, 886,700,000 miles from Sun; 74,500 diameter.
- Uranus=Lonoponor, 1,782,700,000 miles from Sun; 31,566 diameter.
- Neptune=Jinoar, 2,794,300,000 miles from Sun; 30,199 diameter.
- Pluto=Opikimanaras, 3,666,100,000 miles from Sun; 1,864 diameter.
- NI=Montonanas, 570,000,000,000 miles from Sun; solid matter; 7000 miles diameter.
- NII=Suvurutarcar, 830,000,000,000 miles from Sun; 18000 miles diameter; hydrogen, ammonia.
- NIII=Bikalamanar, 1,600,000,000,000 miles from Sun; 46000 miles diameter; hydrogen, ammonia.
An as yet undiscovered planet might be orbiting at the dark fringes of the solar system, according to new research.
Too far out to be easily spotted by telescopes, the potential unseen planet appears to be making its presence felt by disturbing the orbits of so-called Kuiper belt objects, said Rodney Gomes, an astronomer at the National Observatory of Brazil in Rio de Janeiro.
Kuiper belt objects are small icy bodies—including some dwarf planets—that lie beyond the orbit of Neptune.
What's intriguing, Gomes said, is that, according to his new calculations, about a half dozen Kuiper belt objects—including the remote body known as Sedna—are in strange orbits compared to where they should be, based on existing solar system models.
The objects' unexpected orbits have a few possible explanations, said Gomes,...."But I think the easiest one is a planetary-mass solar companion"—a planet that orbits very far out from the sun but that's massive enough to be having gravitational effects on Kuiper belt objects.
If there's no distant world, Gomes concludes, the models don't produce the highly elongated orbits we see for six of the objects.
How big exactly the planetary body might be isn't clear, but there are a lot of possibilities, Gomes added.
Based on his calculations, Gomes thinks a Neptune-size world, about four times bigger than Earth, orbiting 140 billion miles (225 billion kilometers) away from the sun—about 1,500 times farther than Earth—would do the trick.
But so would a Mars-size object—roughly half Earth's size—in a highly elongated orbit that would occasionally bring the body sweeping to within 5 billion miles (8 billion kilometers) of the sun.
And Hal Levison, an astronomer at the Southwest Research Institute in Boulder, Colorado, says he isn't sure what to make of Gomes's finding. "It seems surprising to me that a [solar] companion as small as Neptune could have the effect he sees," Levison said.
They leave out the possibility, that there could be multiple bodies with varying sizes, whose sum causes the distortions, osit.
For a good example of the method cited above to discover by inference, the presence of other objects, watch this.
