+NASA Exoplanet Query App Solution
+
+To address the requirements and constraints of the NASA Exoplanet Query app, I propose the following solution:
+
+Data Loading and Storage
+
+To efficiently load the exoplanet CSV data, we can use the following approach:
+
+Use a library like pandas in Python to read the CSV file into a DataFrame.
+Convert the DataFrame into a JSON object using a library like csv2json.
+Store the JSON object in a data structure like a dictionary or a hash table for fast lookups.
+Data Structure and Search Mechanism
+
+To minimize the time required to query the exoplanet data, we can use the following approach:
+
+Use a data structure like a hash table or a trie to store the exoplanet data.
+Implement a search mechanism that uses the hash table or trie to quickly find matching exoplanets based on the selected query values.
+User Interface and Query Panel
+
+To implement the user interface and query panel, we can use the following approach:
+
+Use a web framework like React or Angular to create a user-friendly interface.
+Create a query panel with dropdowns for year of discovery, discovery method, host name, and discovery facility.
+Add 'Clear' and 'Search' buttons to the query panel.
+Use JavaScript events to handle user input and search queries.
+Results Panel and Data Display
+
+To display the matching exoplanet data in a tabular format, we can use the following approach:
+
+Use a library like react-table or angular-material-table to create a table component.
+Display only the queriable fields in the table.
+Use JavaScript events to handle user input and update the table data.
+Bonus Features
+
+To implement the bonus features, we can use the following approach:
+
+Use a library like react-router or angular-router to create hyperlinks to NASA's Confirmed Planet Overview Page.
+Use JavaScript events to handle user input and open the hyperlinks in a new browser tab.
+Use a library like react-sortable-table or angular-sortable-table to add icons and sorting functionality to the table.
