What is the true shape of the earth?
oblate spheroidSince the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid.
The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis..
What is the universe short answer?
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist. … All we do know is that the visible Universe is at least 93 billion light years across.
How does Earth Support Life Class 6?
Answer: The earth has conditions that support life. It is neither too hot nor too cold. It has both water and air, which are both indispensable for life. Presence of oxygen in the air in appropriate proportion supports life.
Which planet is known as Earth’s twin?
VenusVenus is Earth’s evil twin — and space agencies can no longer resist its pull. Once a water-rich Eden, the hellish planet could reveal how to find habitable worlds around distant stars.
Does Australia see the moon upside down?
In Australia, the Moon is “upside down” from the point of view of northern hemisphere viewers. We see a jolly man’s face in the full moon, while their guy looks a bit alarmed. The dark and light patches on the Moon’s surface are reminders of its hectic past.
Do we have 2 suns?
It’s estimated up to 85 percent of all stars could be in binary pairs, or even triple or quadruple systems; and over 50 percent of all Sun-like stars are in binary pairs. … So, if not for some cosmic event or quirk, Earth could have had two suns. But we don’t.
What is on dark side of moon?
Many people use the phrase “the dark side of the moon” to describe something mysterious and unknown. The dark side of the moon is supposed to be the side we never see, the side that faces away from Earth. This side of the moon faces the cold, black expanse of space.
Why don’t we see the other side of the moon?
First, the dark side isn’t really any darker than the near side. Like Earth, it gets plenty of sunlight. We don’t see the far side because “the moon is tidally locked to the Earth,” said John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project.
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
What is the biggest thing ever?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What is the closest celestial body to our earth?
Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.
Why do we see only one side of the moon always Class 6?
e)We always see only one side of the moon, because the moon moves around the earth in about 27 days and it takes exactly the same time to complete one spin.
Why does the moon not spin?
The Moon does not rotate. The Moon does spin on its axis, completing a rotation once every 27.3 days; the confusion is caused because it also takes the same period to orbit the Earth, so that it keeps the same side facing us.
Is one side of the moon forever in darkness?
One lunar side always faces Earth, or is tidally locked, because the moon’s rotation and orbit is closely synced-up with our planet’s. The moon spins about its axis and orbits the sun with Earth, so its night or “dark” side is constantly moving.
Why is one side of the moon dark?
The far side of the moon is called the “dark side” in popular culture because it’s always unseen from Earth and is relatively unknown, not because it lacks sunlight.
Is the American flag still on the moon?
Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. LRO was designed to produce the most detailed maps yet of the lunar surface. …
Is one side of Moon always dark?
The moon is tidally locked to the earth so the same side faces the earth all the time. There is no constantly dark side.
