Answer #1

Although, we still do not know about the true characteristics of the exoplanet, but I'll try to explain based on what are the general findings about the same.

1. The exoplanets usually revolve around wobbly star, a star that has planets that don’t orbit perfectly around its center. From far away, this off-center orbit makes the star look like it’s wobbling. In contrast to this, the planets of our solar system revolve around the sun with is fixed (atleast from our point of reference).

2. Usually the exoplanets are more massive than the earth. For example, Proxima b is about 1.3 times more massive than Earth, which also suggests that the exoplanets have a rocky world.

3. Some of the exoplanets are very bright, much brighter than any of the planets of our solar system. This might be due to closeness to their star or due to extreme environment on the planet.

Hope this helps!

Problem Domain: We are a software development startup whose market has been to provide logistics for restaurants (ordering, table reservation, user reviews, order-ahead etc.) That was all pre-covid. Now with only 25% max capacity at restaurants, more ordering of remote services, the lack of a social dining/shopping experience for the most part, we need to adapt a solution to this area. Most of our customers (restaurants and food services) cannot sustain themselves or need help. We clearly are not a...
