It will take no time at all
From the surface of the sun the heat radiations take 8 minutes to reach the surface of hte earth.
On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.
If you could travel in a straight line from the sun to the earth at 1,000 meters per second,(2,237 miles per hour), the trip would take 4years271days. (rounded)
The distance from Earth to the Sun is approximately 93,000,000 miles. The speed of a rocket/spaceship is about 20,000 mph. So time taken would be 93,000,000/ 20,000 = 4650 hours. 4650 hrs / 24 = 193.75 days. About one half a year. These are fictitious figures for a DIRECT flight. However, astronomic bodies, Earth an Sun and spaceships. move in orbits/ellipses. This is normal Newtonian mechanics. Because everything is moving distances would be greater and the time taken would be longer.
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.
About 8 minutes

Sirius does not orbit the Sun.
