Who rediscovered aristarchus’s model of a heliocentric solar system? copernicus galileo kepler ptolemy

Nicolaus Copernicus.

Explanation:

The theory that the Earth orbits around the Sun is frequently credited to the Polish astronomer Nicholas Copernicus. However, the original author of the heliocentric model was the astronomer Aristarchos of Samos (c. 310 – c. 230 BC). It was this ancient Greek astronomer and mathematician who introduced the earliest known model that located the Sun at the heart of the universe with the Earth rotating around it.

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.
