What did the ancient Greeks call comets?
Well, sweetheart, the ancient Greeks called comets "asteres kuklos," which translates to "hairy stars." Those Greeks sure had a way with words, didn't they? So next time you see a comet streaking across the sky, just remember it's basically a big, hairy star making a fashion statement.
It means "born of the sun". The sun gives life. Without it nothing can live.
How do you spell the names of the planets?
Names of the Major Planets
- Mercury - named after the Roman mythological counterpart of Hermes, the Greek god of messengers, commerce, thieves, and sports. Named as such because of the speed at which it revolves around the Sun.
- Venus - named after the Roman mythological counterpart of Aphrodite, the Greek goddess of love and beauty.
- Earth (also known by its Latin name, "Terra") - named after the titan of the earth from Greek mythology.
- Mars - named after the Roman mythological counterpart of Ares, the Greek god of war.
- Jupiter - named after the Roman mythological counterpart of Zeus, the Greek king of the gods.
- Saturn - named after the Roman god of agriculture and harvest, Saturn. He is the Roman mythological counterpart of Cronus (Kronos), the Greek titan who fathered Zeus.
- Uranus - named after the Greek mythological Father of the Sky, Ouranos. "Uranus" is the Latin translation of "Ouranos".
- Neptune - named after the Roman mythological counterpart of Poseidon, the Greek god of the seas.
Names of the Dwarf Planets
- Pluto - named for a Greek god of the underworld (successor to Hades)
- Eris - named for the Greek goddess of discord
- Haumea - named for the matron goddess of Hawaii
- Makemake - god of fertility who created humanity in the Rapanui myths
- Ceres - asteroid named for the Roman goddess of agriculture
What should you pack to go to Venus planet?
You couldn't survive long on Venus, with current technology. The pressure at the surface is about 100 times the pressure on Earth, the temperature is over 400 °C, and the atmosphere is highly corrosive - so any protection you set up, such as a protective dome, would quickly break down.
If comet Halley's major axis was scaled down to 15 cm how far apart would the foci be?
They would be roughly 14.49 cm apart, given a major axis of 35.6 AU, and perihelion of about .58720 AU. I am assuming that distances from the foci at perihelion and aphelion will be equal or very close to equal. The major axis minus twice the distance at perihelion gives a distance of about 34.426 AU between foci. 35.6 AU is to 15 cm as 34.4 AU is to x cm. This gives about 14.49 cm as the proportional distance between foci with the major axis scaled down to 15 cm.
MVEMJSUNP are the first letters of the nine .?
MVEMJSUNP are the first letters of the nine planets in our solar system in order of their distance from the sun. They stand for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto (although Pluto is now classified as a dwarf planet). This acronym helps us remember the sequence of the planets in our solar system.
How long does it take an icecube to melt in the sun?
An icecube would never reach or come in contact with any physical part of the sun. However, if one were to be able to place an icecube WITHIN the sun and then start the melting process it would vapourize instantly. Instantly. In such a short time it would be hard to argue it even took place.
What is the planet earth's gravitational force?
Ah, the gravitational force of our beautiful planet Earth is what keeps us all grounded and connected to the land beneath our feet. It's like a gentle hug from Mother Nature, pulling us towards the center of the Earth with just the right amount of force. So remember, no matter where you are on this big blue marble, you're always being held close by Earth's loving embrace.
How does the model of the solar system differ from the orbital model of electrons?
We can not differentiate between the solar system and an elliptical orbit. The solar system consists of planets, their satellites, asteroids and comets. Orbit is the path of the members of a star around that centre and these paths may be in elliptical orbits.
enursha is the feeling of being lighter or heavier than your body really is. for example, the earth pulls a force of 1G but if a astronaut was to visit a planet with a gravitational pull of 5G's their body will feel 5 times heavier than it actually is and vice versa if they visited a planet with a gravitational pull of 0.2G's.
What is the average number of moons per planet?
There are 167 known moons around the eight planets of our Solar System. Therefore the average number of moons per planet is 167/8 which gives 20.875 moons.
The question is obviously about our Solar System, not exomoons, nor the whole universe.
Please add your comments to the discussion board: That is what it is for.
What is the distance between mercury and Saturn?
The distance between Mercury and Saturn varies as they both orbit the Sun at different speeds and distances. On average, Mercury is about 77 million kilometers away from Saturn. However, their distance can range from as close as 77 million kilometers to as far as 1.6 billion kilometers depending on their positions in their respective orbits.
Differetiate between solid earthing and ELCB?
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.
What two planets are farthest apart?
Neptune and Mercury are the two planets farthest apart in our solar system. This is because Neptune is the farthest planet from the Sun, while Mercury is the closest. The distance between Neptune and Mercury can vary greatly due to their elliptical orbits around the Sun.
How do the distances between the inner planets compare to the distance between the outer planets?
The orbits of the four inner planets are much closer, all orbiting the sun within ¼ billion km. The outer planets are more spread out, but are much larger in size. Their distances roughly double each time as you go out from Jupiter.
Average distances of inner planets from sun;
Mercury, 57,909,175km
Venus, 108,208,930km
Earth, 149,597,890km
Mars, 227,936,640km
Average distances of outer planets from sun;
Jupiter, 778,412,010km
Saturn, 1,426,725,400km
Uranus, 2,870,972,200km
Neptune, 4,498,252,900km
What divide planet in two sets?
god ,and the correct question is, who divided the planests in two sets?
2 stars could certainly be considered congruent. This really just depends on the plane the stars fall on for example.
What did nicolaus Copernicus find out?
He discovered that the Earth and all of the planets revolve around the Sun.
What was the controversial idea of Nicolaus Copernicus?
He proved that earth is not the center of the universe.
