Usually such distances are measured either in light-years, or in parsecs.
There are two main units of distance used for measuring space distances, they are solar units and light years
The stars in Leo the Lion (and all the other constellations) are not next to each other. They are all very different distances from Earth and therefor can't be measured in those terms.
measuring distances in the solar system.
Yes. The planets are much closer to our star, "The Sun" than to other stars out there. In fact, Earth is only 149,600,000 Km away from the Sun! But to travel to the next closest star, you would have to travel at the speed of light (300,000 Km/sec) for 4 years!
Parallax
Stellar distances, like the distances of stars and galaxies from Earth
Light years
There are two main units of distance used for measuring space distances, they are solar units and light years
by the property of reflection or electromagnetic waves
parsecs or light years
Distances are measured in metres.
In SI units. Depending on the scale, they are measured in kilometres, metres, centimetres, millimetres etc.
They measure them in light-years.
in the solar system, distances are measured in AU's which stand for atronomical units.
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
Length can be measured in feet, inches and centimetres
because the stars are very far away so the astronomers use light years
