What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.
Some astronauts have likened the smells of space to walnuts.

What is the shape of the earth for Class 3?
The shape of the Earth The Earth is a round ball. However, it is not perfectly round. It is slightly flattened at the top and bottom. Astronauts have seen the Earth from outer space.
Why is space black?
At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day.
Why is the earth shaped the way it is?
Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.
Are all planets round?
The Sun and all eight planets of the solar system are round. Why? The gravitational force of a planet’s mass pulls all of its material toward the center, smoothing out any jarring non-roundness. Many of the smaller bodies of the solar system are not round because their gravity is not enough to smooth out their shape.
Is the Earth lumpy?
The reason Earth appears lumpier is because it does not have a uniform mass – which is one of the key elements in measuring gravity. If you could sample different sections of Earth’s mantle, you would get different materials of varying densities.
Is the Earth potato shape?
A sleek satellite orbiting Earth has confirmed that the planet is not the simple squashed sphere we often imagine it to be. It is, in fact, more like a lumpy potato.
What is the weight of earth?
5.972 × 10^24 kgEarth/Mass
Why are heavenly bodies round?
Celestial bodies are spherical in shape because of gravity. Whenever enough mass gathers close together, the resultant gravity, which follows the inverse square law, pulls equally in all directions and results in a spherical shape.
What is the true shape of the earth answer?
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 the Earth really looks like?
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. … Water covers most of Earth. The white swirls are clouds.
What features of the Earth enables life to exist?
A special planet: the habitable Earth What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
What are the 5 Earth systems?
Five parts are called the geosphere, hydrosphere, atmosphere, cryosphere, biosphere.
Why does the water not fall off the earth?
This makes sense, as without gravity to tug downward, the forces governing the objects are all the same. So, the water drop (and air bubble) form themselves so they occupy a shape having the least amount of surface area, which is a sphere. On Earth, gravity distorts the shape, but not in space.
How was Earth created?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
Why are asteroids not round?
Smaller asteroids are generally not round. In fact, they are jagged, fragmented, and irregular in shape. This is because small asteroids have very weak gravitational pulls, meaning they cannot pull all the material surrounding them towards their center equally.
Is the Earth lumpy or perfectly round?
The Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape.
What planet is the closest to the sun?
MercuryZipping around the sun in only 88 days, Mercury is the closest planet to the sun, and it’s also the smallest, only a little bit larger than Earth’s moon.
