Answer 2

Neutron Stars

Neutron stars are fascinating celestial objects with unique characteristics. Let's go through the given statements and determine which ones are true.

1. Neutron stars do not exceed 2-3 solar masses Neutron stars are extremely dense, and their mass is typically between 1.4 and 3 solar masses. They can indeed exceed 2-3 solar masses. [[1]]

2. They have a diameter comparable to the diameter of the Earth Neutron stars are incredibly dense, and their diameter is relatively small compared to other celestial bodies. Their diameter is typically on the order of 10-20 kilometers, which is much smaller than the Earth's diameter. [[2]]

3. They have a density of over 200 million tons per cubic centimeter Neutron stars are known for their incredibly high density. Their density can indeed exceed 200 million tons per cubic centimeter, making them one of the densest objects in the universe. [[3]]

4. They have a density on the order of 100 kg per cubic centimeter This statement is not accurate. Neutron stars have a much higher density than 100 kg per cubic centimeter, as mentioned in the previous point.

5. They have a density comparable to the density of an atomic nucleus Neutron stars do have a density comparable to the density of an atomic nucleus. This is a defining characteristic of neutron stars. [[4]]

6. They have a diameter on the order of 10-20 kilometers As mentioned earlier, the typical diameter of a neutron star is indeed on the order of 10-20 kilometers. [[2]]

Based on the search results, the correct statements are: - Neutron stars do not exceed 2-3 solar masses - They have a diameter comparable to the diameter of the Earth - They have a density of over 200 million tons per cubic centimeter - They have a density comparable to the density of an atomic nucleus - They have a diameter on the order of 10-20 kilometers
