DESCRIPTION:In just 30 years\, we went from no known exoplanets to more th
 an 5000 known exoplanets. This growing sample of exoplanetary systems allo
 ws us to study their mass-radius relationship or lack thereof and their co
 nnection with their host stars\, if any. Despite all these wonderful exoti
 c new worlds\, we are yet to find a planet like the Earth. Our biggest cha
 llenge is the star itself creating signals due to its magnetic variability
  that mimic or hide the planetary signals. We have started observing the S
 un as a star to understand these stellar nuisance signals giving promising
  avenues. In this talk\, I will give you an overview on the star-planet re
 lationship\, our efforts to find and characterise small planets\, and how 
 our own Sun is helping to lead the way to find another Earth.
