that depends on where pluto is in its orbit
(think of sirius as the hub of your front bike wheel, the sun as the hub of the back wheel and pluto as the valve for the back wheel inner tube)
with the vast distance from the sun to sirius (8.6 light years) the percentage of how much closer it is to pluto or the sun will be tiny, but its still a measurable difference. (pluto is only about 4 light HOURS from the sun)
The Earth is much closer to the sun than it is to Pluto.
Jupiter is closer to the Sun.
It is closer to us.
The sun appears brighter than Sirius does because it is about half a million times closer to us.
Uranus
Neptune is closer to the sun but because of Pluto's elliptical orbit, Neptune is farther away form the sun for 20 years. Neptune is closer to the sun but because of Pluto's elliptical orbit, Neptune is farther away form the sun for 20 years.
Venus is much closer to the Sun then Pluto.
Yes, Pluto is slightly warmer when it is closer to the Sun.
Because earth is much, much closer to the sun that Pluto.
ceres
Pluto is farther from the sun than any of the 8 major planets. There are other dwarf planets farther from the sun than Pluto though.
In about 2227 A.D., their orbits will cross and Pluto will be closer to the sun for 20 years. Then, the orbits will cross again and Neptune will be closer for 228 years.
