## How long would it take to travel to Pluto?

The \$720 million New Horizons mission launched in January 2006, speeding away from Earth at a record-breaking 36,400 mph (58,580 km/h). Even at that blistering pace, it still took the probe 9.5 years to reach Pluto, which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.

## 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.

## How many suns are within 100 light years of Earth?

abundance and proximity. At least 76 stars of spectral type “A” (not including white dwarf stellar remnants) are currently believed to be located within 100 light-years or (or 30.7 parsecs) of Sol.

A stars within 100 light-years.

Name or Designation Denebola A3 V 2.3 Leo Bet Leo, HR 4534

## How many stars are in 1000 light years of Earth?

Only about 4 stars per 1000 cubic light years. The distribution of stellar luminosities in the Solar Neighborhood is dominated by low-mass stars. Most main-sequence stars are faint, cool M-type dwarfs (red dwarfs). Stars like the Sun are relatively rare.

## How fast we can travel in space?

Think again. For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

## How long would it take to travel to Mars?

The cruise phase begins after the spacecraft separates from the rocket, soon after launch. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).

## How long would it take to drive to the sun at 100 mph?

So, if someone was traveling 100 miles per hour from earth to the sun, it would take just over 106 years.
