Fission and fusion are different nuclear reactions.
No, this is the fusion reaction which occurs in the sun and other stars. See the link below.
Fission does not occur in the sun, it is fusion which produces the sun's energy
The Sun get it power by nuclear FUSION not by nuclear fission.

In the so-called "hydrogen bomb" or fusion bomb, yes, there is energy released from the same reaction (hydrogen fusing to helium) as in the Sun.However, many if not most atomic bombs are fission bombs that do not involve fusion. In a fission bomb, the nuclei of uranium atoms are split, converting some of their mass to energy.All current fusion bombs include fission reactions to trigger the greater energy release from fusion. But most of the energy in very large fission-fusion bombs comes from a third-stage reaction: the fusion causes an exceptionally powerful fission reaction in a uranium shell around the bomb. This called a Teller-Ulam device or fission-fusion-fission bomb.
Little Boy is a Nuclear Fission Reaction
Nuclear fission and reaction, intense heat.

explain how a fusion reactor would be similar to a fission reaction
Not fusion, but a fission reaction.
