Question

arcturus is a star whose surface temperature is 4290 k. what is most likely the color of arcturus? what is most likely the mass of arcturus? about solar masses color surface temperature (k) ave. mass (solar mass) red under 3500 0.3 orange 3500 - 5000 0.8 yellow to white 5000 - 6000 1.1 white 6000 - 7500 1.7 white to blue 7500 - 11,000 3.2 blue 11,000 - 25,000 18 blue > 25,000 60

Explanation:

Step1: Identify temperature - color range

The surface temperature of Arcturus is 4290 K. This temperature falls within the 3500 - 5000 K range which corresponds to orange color.

Step2: Identify temperature - mass relation

Since the temperature of 4290 K is in the 3500 - 5000 K range, the average mass for this range is 0.8 solar masses.

Answer:

Orange
0.8
