Answer:

measure the parallax and use it in calculations

Step-by-step explanation:

The best method to calculate the approximate distance of a star from Earth based on observations from two positions in Earth's orbit (summer and winter) is to measure the parallax and use it in calculations. Parallax is the apparent shift in the position of a nearby object when viewed from different perspectives, and it is commonly used in astronomy to determine the distance to stars.

Therefore, the correct option is:

measure the parallax and use it in calculations

Answer:

The answer is "measure the parallax and use it in calculations".

Step-by-step explanation:

In this question, the above choice is correct because, in the summer and winter, light is observed from both parts of a planet. An astronomer can once, again and 6 weeks later calculate the position of a star and then compute the perceived shift of location. It measures which utilizes parallax and its best method for calculating the approximate distance between the star, as well as the planet.
