The Galactic Center is approximately 8 kiloparsecs (26 000 ly) away from Earth in the direction of the constellations Sagittarius Ophiuchus and Scorpius where the Milky Way appears brightest visually close to the Butterfly Cluster (M6) or the star Shaula south to the Pipe Nebula.

What distance is 1 light year closest to?

A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second and there you have it: one light-year. It’s about 5.9 trillion miles (9.5 trillion km).

Whats the distance of a light year?

6 trillion miles
A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year or 6 trillion miles (9.7 trillion kilometers). On the scale of the universe measuring distances in miles or kilometers doesn’t cut it.May 31 2019

Bottom line: The sun is about 1/3 the distance from the center of the Milky Way galaxy to its outer edges. It’s located in a smaller spiral arm between two large arms called the Orion Arm.

How long would it take to get to Mars?

The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey engineers have several opportunities to adjust the spacecraft’s flight path to make sure its speed and direction are best for arrival at Jezero Crater on Mars.

Is a light year?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186 000 miles (300 000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

The Milky Way is simiar in many ways to M31 the Andromeda Galaxy. Our Sun lies about 30 000 light years out from the Galactic Center. The Earth lies close to the center of the Galaxy.

What use are 21 cm radio waves to galactic astronomers?

The 21-centimetre radiation readily penetrates the clouds of interstellar dust particles that obstruct optical observations deep into the galactic centre and thus allows the mapping of the galaxy’s spiral structure.

How many Earth years is a Lightyear?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.
