What are the 13 planets in our solar system?
Here are the planets listed in order of their distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
An easy mnemonic for remembering the order is “My Very Educated Mother Just Served Us Noodles.”.
Does space have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
How old is our Earth?
4.543 billion yearsEarth/Age
Which is bigger galaxy or universe?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
What is the oldest star in the universe?
Methuselah starThis Digitized Sky Survey image shows the oldest star with a well-determined age in our galaxy. Called the Methuselah star, HD 140283 is 190.1 light-years away. Astronomers refined the star’s age to about 14.3 billion years (which is older than the universe), plus or minus 800 million years.
What are the 15 planets?
Who created the planets?
The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun’s formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
Can humans travel to another galaxy?
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. … Traveling to the Andromeda Galaxy, 2.54 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop.
What is the largest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
How old is the solar system in comparison to the universe?
How Old is the Universe? Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years.
