How is scientific notation used in the galaxy?
As far as we know, we only use scientific notation here on Earth, for the computing of very large numbers (like the distance between planets) or very small numbers (like the radius of a hydrogen atom).
What is the best example of the purpose of scientific notation?
Any number that is very large, or very small (near zero). For example, the mass of the Sun in kilograms (large), the distance to the M31 galaxy in meters (large), or the mass of the electron in kilograms (small).
Why do the scientist use scientific notation to measure in the universe?
Using basic units from the SI system,the nearest star to the sun is approx 40,218,000,000,000,000 metres away.the furthest known galaxy is 126,800,000,000,000,000,000,000,000 metres away.the mass of the sun is 1,989,000,000,000,000,000,000,000,000,000 kilograms.the mass of the Milky Way Galaxy is approximately a trillion times as large.It is easier to make mistakes when working with such large numbers. Furthermore, in many cases, the numbers are known to only few significant digits so the trailing zeros are no more than place holders. That is why scientific notation is so useful.
What is a sentence using the word analogous?
The word 'analogous' means 'similar', 'comparable'. It is however, of a higher register than those two, and is mostly used in scientific writing. Here's an example of the word in use, taken from a scientific website: "Mind-blowing: Distance between local stars in our galaxy is analogous to 2 grains of sand miles apart"
How is the scientific notation useful to astronomers?
Astronomers often have to deal with large numbers, because the universe is very large and most of the universe is very distant from the Earth. For example, the size of the Milky Way galaxy on its long axis is 200,000 light years, and a light year is about 7,000,000,000,000 miles, so if I wanted to tell you how many miles long the galaxy is on its major axis, I could say it is 14,000,000,000,000,000,000 miles, or much more conveniently, I could say that it is 1.4 x 1019 miles.
What is the scientific notation of the Andromeda Galaxy having at least 200000000000 stars?
This can be expressed as: "The Andromeda Galaxy contains at least 2 x 1011 stars".
How far away is earth from the Andromeda galaxy in kilometers in scientific notation?
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
Who measured the distance of Andromeda Nebulae and named after him?
Andromeda Galaxy
Is there a galaxy called Andromeda?
Yes. The Andromeda Galaxy is the nearest spiral galaxy to our own and is the most distance object visible to the naked eye.
How far is the star on near side of Andromeda galaxy?
The distance to the Andromeda Galaxy is estimated at 2.5 million light-years. The distinction between "near side" and "far side" is irrelevant, since the diameter of the Andromeda Galaxy is probably less than the error in the distance estimation.
How far from earth is the farthest star on the Andromeda galaxy?
Just about as far as the closest star in the Andromeda Galaxy. The diameter of the Andromeda galaxy is ... well, quite huge, but still relatively small, compared to the distance between us and the Andromeda Galaxy. And I believe this diameter may still be smaller than the uncertainty in the distance estimate!
What are the planets in Andromeda galaxy?
The Andromeda galaxy is a separate galaxy from our Milky Way and has its own set of planets. However, due to the vast distance between our galaxies, we are currently unable to observe individual planets in the Andromeda galaxy.
How can distance to the Andromeda galaxy be measured?
The distance to the Andromeda galaxy can be measured using various methods, such as parallax measurements, standard candles (e.g., Cepheid variables), and redshift. These methods help astronomers determine the distance of Andromeda from Earth with good accuracy.
What is the distance between Milky way Galaxy and Andromeda Galaxy?
100,00 light years away.
Is the Andromeda galaxy an elliptical galaxy?
The Andromeda Galaxy is a spiral galaxy.
How far is the Andromeda galaxy in miles?
The Andromeda galaxy is approximately 2.537 million light-years away from Earth. In miles, this distance is approximately 14,800,000,000,000,000,000 miles.
Is the sun Neptune or Andromeda galaxy closest in distance to the earth?
The Sun is the closest of the three, followed by Neptune, then Andromeda.
