The star that is nearest to us is really our own Sun, which is 93,000,000 miles away (150,000,000 km). Proxima Centauri is the next nearest star in terms of distance. It is located around 4.3 light-years away, or approximately 25,300,000,000,000 miles away (about 39,900,000,000,000 kilometers).

What is the distance from the nearest star to the Earth?
A light-year is the distance traveled by light in a single year. What is the distance between you and me? One light-year may be calculated by multiplying the number of seconds in a year by the amount of miles or kilometers that light travels in a second, and the result is one light-year. It is about 5.9 trillion miles in length (9.5 trillion km).
How long would it take to travel 4 light-years?
Last year, researchers speculated that our nearest neighbor, Proxima Centauri, may contain a number of potentially habitable exoplanets that may meet the criteria for life on our planet. When measured in light years, the distance between Earth and Proxima Centauri is 4.2 light-years, which would take around 6,300 years to traverse with current technology.
How far is the closest black hole?
A black hole with three times the mass of the sun has been discovered by astronomers, making it one of the tiniest black holes discovered to date. It also happens to be the nearest known black hole, located only 1,500 light-years away from the planet Earth.
How long would it take to get to Proxima B?
It took nine and a half years to complete the journey. While New Horizons was moving at speeds in excess of 52,000 miles per hour, it would take around 54,400 years for the spacecraft to reach Proxima Centauri.
How many Earth years is a Lightyear?
A light-year is the distance that light travels in one year on the surface of the planet. One light-year is equal to approximately 6 trillion miles (9 trillion km). Light travels a certain distance in one year, which is measured in light years (L) (it is about ten trillion kilometers, or six trillion miles). In astronomical terms, one light year is equivalent to approximately 6.5×105 earht years.
How many Earths can fit in the sun?
It is estimated that around 1.3 million Earths may be contained within the sun’s volume when the volume of the sun is divided by the volume of the Earth.
How long would it take to get to the sun?
Flight to the sun is faster: it would take 169,090 hours to travel at 550 miles per hour to reach the solar from Earth. If you flew at 550 miles per hour, it would take 7,045 days to get there. To go there by plane, it would take 19.3 years.
How many galaxies are there?
There are about 125 billion (1.25 1011) galaxies in the visible universe, according to the Hubble Deep Field, an extraordinarily long exposure of a comparatively empty section of the sky taken by the Hubble Space Telescope.
Which is the second nearest star to the Earth after the sun?
Earlier this year, scientists found a planet around Proxima Centauri, the nearest star to our sun and only 4 light-years away. The planet was identified in 2016 and orbits the star Proxima Centauri. They now think they have discovered an exoplanet orbiting Barnard’s star, which is only 6 light-years distant and is the second-closest star system in the universe.
What is the nearest star to Earth after the sun?
Alpha Centauri A and Alpha Centauri B are the two major stars in the constellation, and they constitute a binary pair. According to NASA, they are approximately 4.35 light-years away from Earth. With a distance of around 4.25 light-years from Earth, the third star is known as Proxima Centauri or Alpha Centauri C, and it is the nearest star to the planet other than the sun.
